Re: getting rid of EOL character ?
hi John, In the previous language I used, when reading a line by readline, the EOL character was removed. Very interesting; how did you distinguish between EOF and an empty line? Did you need to call an isEOF() method before each read? Yes indeed, and I admit it needs some more coding ;-) Now I'm reading a text-file with CR+LF at the end of each line, Datafile = open(filename,'r')line = Datafile.readline() now this gives an extra empty line print line and what I expect that should be correct, remove CR+LF, gives me one character too much removed print line[,-2] Stef, that would give you a syntax error. I presume that you meant to type line[:-2] Yes, sorry. while this gives what I need ??? print line[,-1] Is it correct that the 2 characters CR+LF are converted to 1 character ? In text mode (the default), whatever is the line ending on your platform is converted to a single newline '\n' which is the same as LF.

So long as there is a value on the stack for the THEN to pop off, it doesn't matter if it gets there before or after the IF.

In text mode (the default), whatever is the line ending on your platform
is converted to a single newline '\n' which is the same as LF.
Using line[:-1] is NOT recommended, as the last line in your file may
not be terminated, and in that case you would lose the last data character.
Is there a more automatic way to remove the EOL from the string ?
line = line.rstrip(\r\n) should take care of it. If you leave out
the parameter, it will strip out all whitespace at the end of the
line, which is what I do in most cases.
If you want *exactly* what is in the line, use line.rstrip('\n') -- this
will remove only the trailing newline (if it exists).
If you want to strip all trailing whitespace, use line.rstrip() as
Michael suggested.
Michael, note carefully that line.rstrip('\r\n') removes instances of
'\r' OR '\n' -- the arg is a set of characters to be removed, not a
suffix to be removed. In Stef's situation, it works only by accident.
Using that would not always give you the correct answer -- e.g. if your
(Windows) file had a line ending in CR CR LF [I've seen stranger].
I knew that about line.rstrip, but didn't consider the possibility of
\r\r\n, while still wanting the first \r. Yuck.
Honestly, I almost always use line.rstrip()--it is seldom that I care

I see two problems here: - Also from my error in the last posting it's quite clear that the RPL statement doesn't do what one would suppose. There are bad programmers in every language, but RPL conditional blocks aren't the cause of them.

Isn't this what Python always tries to avoid: Doing something different from what is obvious. RP order doesn't fit in Python, IMHO. I agree that blindly trying to copy RP notation into Python wouldn't work. - What should the expression's value be if the else is omitted? None? What's it in the original? I can't imagine a use case here since I always have two alternatives when I use a if b else c. In RPL, there are no expressions. RPL programs are constructed from data and commands, not expressions. So you shouldn't think of garbage can full if fetch out garbage [else don't] as an expression. Think of it as a block, equivalent to the Python: if garbage_can_full: fetch out garbage else: don't except that you can write it as a single line. Newlines in RPL are just another sort of whitespace, with no special significance. If the else clause is missing, then nothing is executed and processing simply continues past the end of the block. I agree with you that in the case of Python _expressions_, it doesn't make sense to have a missing else part. But in the case of RPL, it is perfectly natural for the else block to be missing. -- Steven. -- http://mail.python.org/mailman/listinfo/python-list

It should be a simple enough job to code in the features the Unix and DOS ping programs have(never stop, change size, change timeout). As I am typing this, I'm looking through ping.c to see what I can glean. It probably won't be much. My experience with C is very little. As in, microscopic.

It would be unusual to want that first \r -- a possibly more likely
scenario might be where your text file contains an extract from a
database, and you need to check that there are no unwanted (e.g.
unprintable) characters in the data (whether at the end of the line,
the middle, or the start).
In any case I think that you are missing the point that when reading a
normal text file on Windows with readline, while the line in the file
may be 'foo bar\r\n', what you get from readline is 'foo bar\n' -- so
in normal usage, the \r in your line.rstrip('\r\n') is pointless.
Honestly, I almost always use line.rstrip()--it is seldom that I care
about closing whitespace.
Honestly, I almost always split a line into fields and then for each
field, strip leading and trailing whitespace, and change runs of 1 or
more whitespace characters to a single space -- where whitespace
includes the pesky U+00A0 aka nbsp; which doesn't qualify as
whitespace in a str instance.

I plan to add support of UML CASE tools other than the one supported currently. I would like to learn which UML tools you use (if any), Any piece of paper and anything that can be used to write on it. preferrably if it comes to modeling a Python application. I stll wait for UML to be able to describe common hi-level dynamic languages idioms and patterns without requiring more space and time than source code. I am inclined to agree, though my experience is limited. I work on a project that is trying to model all its software using Enterprise Architect. EA has some nice features, but overall I find it clumsy and frustrating. Some problems are intrinsic to UML (for instance it has no concept of linking use case information to other elements). And I don't know of any way to model functions (only classes). Others are EA's fault. For instance it is very slow and clumsy to add or edit lists of items (such as class methods or database fields). Also, shared development is a pain because there is no concurrent version control (it uses CVS to keep track of revisions, but not in a concurrent way; checking out a package locks out everybody else). Version control of UML models is a tough issue, given the dependencies between models and thinking of visualization of differences between two models. So far my tool only uses one model in one single XMI file, but I have to change this especially since I want to ease the re-use of components between projects. I tried using a competing product but the interporability was terrible. Which brings up another point: it is likely the original poster would need to do a lot of work for each CASE tool supported. Unfortunetaly you are too right! :)) Interoperability via XMI is a nightmare I don't want to dream anymore. For example, in the recent years it would have been much easier to use MagicDraw's OpenAPI with Jython to access models instead of importing its XMI files. The one thing is that MOF, UML and XMI are developing way too fast, so there are many tools but chance is little that they are based on the same standard versions. Additionally I don't know one tool which fully implements the corresponding standard specifications. Not a big surprise since the specifications are really complex and extensive. So, supporting one specific XMI format of one UML tool is not that complicated (especially since not all features are needed). But I have still a hard time thinking about an appropriate mapping between all these different standard versions and the differences how they are implemented in the tools. Especially since I want to keep these differences away from the normal tool user. Maybe it will be possible, at least as some compromise. The future will show.

Re: More urllib timeout issues.
John Nagle wrote: I thought I had all the timeout problems with urllib worked around, but no. socket.setdefaulttimeout is useful, but not always effective. I'm setting that to 15 seconds. If the host end won't open the connection within 15 seconds, urllib times out. But if the host end opens the connection, then never sends anything, urllib waits for many minutes before timing out. Any idea how to deal with this? And don't just say use urllib2 unless you KNOW it works better there and can explain why. I finally have M2Crypto and urllib playing well together, and don't want to mess with that. For some wierd reason, several UK academic sites have this behavior, including soton.ac.uk. If you try to open that in a browser, the browser just sits there, and eventually, after several minutes, displays The site is taking too long to respond. What's the current status in this area? Some patches to sockets were proposed a while back. There's a long history of trouble in this area, and some fixes, but nothing that just works. The sockets module has two timeout settings (socket.setdefaulttimeout and sock.settimeout, the M2Crypto module has two (sock.set_socket_read_timeout and sock.set_socket_write_timeout), and none of them play well together or with the urllib/urllib2/httplib level and the blocking/non blocking socket distinction. What we really should have is something like this: Sockets should have set_socket_connect_timeout set_socket_read_timeout set_socket_write_timeout which set an upper limit on how long a socket can go with a request for a connect, read or write pending but without progress on the connection. This needs to be independent of select poll timeouts, and these timeouts should work on blocking sockets. The existing socket function settimeout should set all of the above, and socket.setdefaulttimeout should set the default value for settimeout to be used on new sockets. SSL and M2Crypto, which wrap socket functionality, should understand all the above functions. HTTPlib, urllib, and urllib2 objects should understand settimeout Making the connect/read/write timeout distinction at that level probably isn't worth the trouble. Then we'd have a reasonable network timeout system. We have about half of the above now, but it's not consistent. Comments? The only comments I'll make for now are 1) There is work afoot to build timeout arguments into network libraries for 2.6, and I know Facundo Batista has been involved, you might want to Google or email Facundo about that. 2) The main reason why socket.setdefaulttimeout is unsuitable for many purposes is its thread-unsafe property, so all threads must use the same default timeout or have it randomly change according to the whim of hte last thread to alter it. 3) This is important and sensible work and if properly followed through will likely lead to serious quality improvements in the network libraries. regards Steve -- Steve Holden+1 571 484 6266 +1 800 494 3119 Holden Web LLC/Ltd http://www.holdenweb.com Skype: holdenweb http://del.icio.us/steve.holden -- Asciimercial - Get Python in your .sig and on the web.

Re: creating an object from base class
Ian Clark wrote: Quote iogilvy: i wish to have some extended functionality added to sockets i can create my own socket class class mysocket(socket.socket): and all should be fine. Except, the sockets are created for me by the accept method, listening on port. So how can i take the standard socket created for me and create a 'mysocket'. I need a method that will initialise any new properties i have added in my class, but how can i change the class of the socket created? Someone correct me if I'm wrong, but I don't believe it's possible to change the type of objects made from builtin classes. Though if it's a custom class you can, for example: class Foo: pass class Bar: pass obj = Foo() obj.__class__ = Bar Yes, assuming you weren't asking a rhetorical question you will eventually run up against class myClass1(object): pass ... class myClass2(object): pass ... mc1 = myClass1() type(mc1) class '__main__.myClass1' mc1.__class__ = myClass2 type(mc1) class '__main__.myClass2' 2 . __class__ = myClass1 Traceback (most recent call last): File stdin, line 1, in module TypeError: __class__ assignment: only for heap types This doesn't qualify as error message of the year, but it clearly tells you you aren't going to get around the prohibition. We also see o = object o.__class__ = myClass2 Traceback (most recent call last): File stdin, line 1, in module TypeError: can't set attributes of built-in/extension type 'object' which gives a much better error message. Of course it'll probably only take Alex Martelli a few minutes to find a workaround or counter-example. One option is to make your custom socket a wrapper around socket.socket and then pass through the calls you don't want to handle to socket.socket. The downside to this is there are quite a lot of methods that need to be accounted for. For example: class CustomSocket: def __init__(self, socket): self.socket = socket def connect(self, address): self.socket.connect( address + '.some.tld' ) [etc] ... s = server_socket.accept() s = CustomSocket(s) This technique is formally called delegation if you want to Google it. Another approach you might want to look at is populating your object at runtime through a function. This won't give it the type you want, but it will give it any methods and attributes it would have gotten from your class with the added benefit of it still being of type socket.socket. Example: def modify_socket( socket ): socket.cabbages = 'Yuk' socket.apples = 'Yum' def info(): print 'Cabbages? %s\nApples? %s' % (socket.cabbages, socket.apples) obj.show_info = info ... s = server_socket.accept() modify_socket( s ) s.show_info() Cabbages? Yuk Apples? Yum s.apples = 'Yummie' s.show_info() Cabbages? Yuk Apples? Yummie type(s) class 'socket._socketobject' Of course that approach sucks if sockets happen to have an organes or apples attribute that's used in the inner workings of the class. This is when the C++ devotees start screaming about protected and private variables.

I'm trying to see if by being clever, I can factor out the common code of
the four different functions and still end up with what they create ending
up in the namespaces where they are intended to reside in. Does this make
sense or am I way off base?
Even if you *can* factor out the common code there's no reason why that
shouldn't go in a fifth module that the other four import ...

Re: More urllib timeout issues.
Steve Holden wrote: John Nagle wrote: Then we'd have a reasonable network timeout system. We have about half of the above now, but it's not consistent. Comments? The only comments I'll make for now are 1) There is work afoot to build timeout arguments into network libraries for 2.6, and I know Facundo Batista has been involved, you might want to Google or email Facundo about that. 2) The main reason why socket.setdefaulttimeout is unsuitable for many purposes is its thread-unsafe property, so all threads must use the same default timeout or have it randomly change according to the whim of hte last thread to alter it. It has other problems. If you set that value, it affects socket blocking/non blocking modes. It can mess up M2Crypto, causing it to report Peer did not return certificate. 3) This is important and sensible work and if properly followed through will likely lead to serious quality improvements in the network libraries. Agreed. regards Steve I took a look at Facundo Batista's work in the tracker, and he currently seems to be trying to work out a good way to test the existing SSL module. It has to connect to something to be tested, of course. Testing network functionality is tough; to do it right, you need a little test network to talk to, one that forces some of the error cases. And network testing doesn't have the repeatability upon which the Python test system/buildbot depends. It's really tough to test this stuff properly. The best I've been able to do so far is to run the 11,000 site list from the Webspam Challenge through our web spider. Here's a list of URLs from our error log which have given us connection trouble of one kind or another. Most of these open an HTTP transaction, but for some reason, don't carry it through to completion properly, resulting in a long stall in urllib. blaby.gov.uk boys-brigade.org.uk cam.ac.uk essex.ac.uk gla.ac.uk open.ac.uk soton.ac.uk uea.ac.uk ulster.ac.uk So that's a short, but useful, set of timeout test cases. Those are the ones that timed out after, not during, TCP connection opening. It's interesting that this problem appears for the root domains of many English universities. They must all run the same server software. Some of these fail because robotparser, which uses urllib, hangs for minutes trying to read the robots.txt file associated with the domain.

Re: Numbers and truth values
Szabolcs [EMAIL PROTECTED] wrote: ... True = 2 # DON'T DO THIS!!! 2 == True True But shouldn't Python forbid this? Is it possible to get a warning when unintentionally redefining built-in thing? Python can be changed to make some non-reserved builtin identifiers into reserved words, going through a stage where this is allowed but gives a warning. This happened in recent years for assignments to None, which were legal back in 2.2 and earlier: $ python2.3 -c'None=23' string:1: SyntaxWarning: assignment to None $ python2.4 -c'None=23' File string, line 1 SyntaxError: assignment to None ...and, as you can see, gave syntax warnings in 2.3, becoming syntax errors in 2.4 and later versions. However, Python has a somewhat large and growing number of builtin identifiers: $ python2.3 -c'print len(__builtins__.__dict__)' 124 $ python2.4 -c'print len(__builtins__.__dict__)' 128 $ python2.5 -c'print len(__builtins__.__dict__)' 133 while keywords (reserved words) are far fewer, and more constrained in their growth: $ python2.3 -c'import keyword; print len(keyword.kwlist)' 29 $ python2.4 -c'import keyword; print len(keyword.kwlist)' 29 $ python2.5 -c'import keyword; print len(keyword.kwlist)' 31 so, making all builtins into keywords is unlikely to happen: it would break a lot of existing code in exchange for a minor benefit. It _would_ surely be possible to make Python behave this way only when a certain commandline flag or environment variable is present, e.g. by tweaking the implementation of the relevant bytecodes: def f(): ... global aglobal ... aglobal = 23 ... alocal = 45 ... dis.dis(f) 3 0 LOAD_CONST 1 (23) 3 STORE_GLOBAL 0 (aglobal) 4 6 LOAD_CONST 2 (45) 9 STORE_FAST 0 (alocal) 12 LOAD_CONST 0 (None) 15 RETURN_VALUE STORE_GLOBAL and STORE_FAST. However, this might slow down normal operation (by needing to check some flag at each STORE_...). Perhaps a better approach is to perform your checking with a tool that is _separate_ from Python proper. Wouldn't it be great to have a tool to check Python sources, one which we could name, for example, pychecker, that we could run as follows...: $ cat ba.py False = 23 $ pychecker ba.py Processing ba... Warnings... ba.py:1: (False) shadows builtin ba.py:1: Should not assign to False, it is (or will be) a builtin Rejoyce! http://pychecker.sourceforge.net/ ... There are other tools to perform such checks, such as pylint, http://www.logilab.org/857, which is quite a bit more complicated but can perform many more checks (and can be integrated into PyDev, an Eclipse add-on which some people like to use as a Python IDE), and, I believe, a few other with slightly different slants (such as pyflakes, http://www.divmod.org/projects/pyflakes, which does fewer checks but does them faster and in a way that's safe against potentially-evil code). By the way, both of these tools (and many other tools, and a lot of other useful tips) are mentioned at http://www.python.org/doc/faq/programming/ , the Python Programming FAQ (it's a bit dated, but if you find any problem with it, just like with any other piece of official Python docs, bugs and suggested patches are welcome at the usual location, http://sourceforge.net/projects/python ). Perhaps one day some variant of pychecker and/or pylint can be integrated in Python itself, and executed (for example at each import) if that's indicated by some appropriate flag or environment variable; however, for us command-line dinosaurs, the people who prefer running python at a shell prompt (rather than more advanced things such as ipython, or IDEs such as PyDev, IDLE, etc, etc) this doesn't really tend to be that high a priority, as we're quite used to not necessarily auto-integrated tools; it's probably a higher priority to get pychecker or something like that integrated with other IDEs such as IDLE (I don't know, besides PyDev's ability to use pylint, which other such integrations currently exist -- anybody?).

As I understand it, he has a C function that uses stdout and stderr to report errors (perhaps using printf, fprintf, perror and similar functions) and he wants to call it from Python. Reassigning sys.stdout/stderr in Python won't help. One way would be to make an executable from the C code, and call it using the subprocess module or some popen variant. How to pass arguments depends on the application, and may not be efficient. Another way would be to change the C code, adding a FILE parameter (let's call it logfile) and replacing every printf(..., xxx) with fprintf(logfile, ..., xxx); the same for related functions.

My Python annoyances
I'm really annoyed at Python - and not for the reasons already mentioned on this list. Everyone know that programming is supposed to be a dark art, nearly impossible to learn. Computer code is supposed to be something impossible to read to the common person and yet reveal their secrets to the initiated - just remember the code displayed in the Matrix... Python takes all of that away. It is just too readable. Even beginners can quickly learn to read code written by experts. To make it even friendlier to beginners, Python uses ugly double underscores both as prefix and suffix on magic methods to be invoked only by more advanced programmers. What's the fun in hiding the complexity so that beginners can stay away from potential problems. And why, oh why, does raw_input() have to go? Here was at least one good example of something that gave a hint (what does raw mean?) at the underlying complexity. Combined with the evil of the hidden eval in the more obvious input(), there was at least a chance to trip beginners into doing something dangerous. Alas, that will no longer be the case... Python does not even make good use of weird symbols like $ and @ and % to define variable types like Perl does. Now, that's a language to learn if you want to be respected. I think that Georg Brandl had it right in his recent proposal: http://mail.python.org/pipermail/python-dev/2007-April/072419.html If not Perl, perhaps Python should be inspired by a language like C++, full of arcane stuff and, thankfully, requiring typing declaration. This dynamic typing thing makes it just too easy to write working programs quickly, especially combined with the ease of use of the interpreter. And this other thing called duck typing is just too flexible to use. No, Python should be more difficult. It should take a full two minutes to compile a Hello World program on a modern computer. Also, this docstring business has to go. Any programmer should, as a rite of passage, have to spend countless hours reading obscure documentation to learn other people's code before finding out what methods can be used and how they should be used. Having to use things like dir and help just makes it too easy. And don't get me started about the absence of curly braces to define blocks of code. What's the fun in making it so darn visually easy to define such blocks of code, removing the possibility of creating subtle bugs due to the misplacement of a curly bracket.

This is not fair for people that have spent dozens of hours in learning to program using Python! And don't talk to me about functions, classes and methods, not to mention modules. Python makes it too easy to write code in many different styles, trying to please people who like to write only object-oriented code as well as those that follow the more traditional procedural approach. Even functional type people find their way to write code in their preferred method using Python. This is not right. Fortunately, Python has incorporated some newbie-unfriendly features, like metaclasses and, to a lesser extent, decorators which, at last, make use of a special character.

First, you may want
errcode = str(e)
instead of
errcode = e
Second, the empty string is probably because the Exception is
instantiated without a string. E.g.:
str(Exception())
''
Third, you must not be showing us everything, because an Exception can
be used as a key, but does not give an empty string upon printing. You
are definitely not showing us what it looks like when you print
ErrorHash, which would be helpful.
Fourth, that you are creating a table of error codes means that you are
attempting to transmogrify the way python handles exceptions into some
paradigm you have used in a language like FORTRAN and thus are not using
exceptions in their intended way. You might describe the reason you are
generating error codes and gather suggestions about a more pythonic
(i.e. reasonable) approach.

Apparently, the Exception class's __str__() method doesn't print

I can't reproduce your problem (using simpler code of course, yours is

semantically equivalent):

As you can see, the only problem is that two occurrences of the same
error ar kept distinct -- they're distinct instances of the same class
without special hashing or comparison methods, and so are distinct when
considered as keys into a dict. There are of course ways to collapse
them (e.g, use (type(e), str(e)) as the dict key, or, many others), but
at any rate this does not appear to have anything to do with the problem
you report.
Could you perhaps post a complete, self-sufficient short script or
interactive interpreter session, such as the few lines I've just copied

Re: Video: Professor of Physics Phd at Cal Tech says: 911 Inside Job
here's a question that came-up recently, in battling with the controlled-demo advocates at teh Promenade: how is it that the metal was still molten, after weeks? it seems taht an additional hypothesis is required, to explain that. because I doubt that there was sufficient nukular material left-over from a hypothetical suitcase-device. there are similar question, from what I recall of Jones' report (I just stopped at the first thing that seemed funny, today .-) publications:http://www.physics.uiowa.edu/~cgrabbe/writing/ research.html demanding of INTELLECTUAL HONESTY. thus: this was basically assuming that floor 50 of a 100-floor building started the collapse?... interesting analysis; I hope to look at it, again, later. have you seen the old analysis by the MIT Head Welder, that I only saw a couple of weeks ago? At time t=0, the top 50 floors begin to fall, independently of each other. The first actual impact is when floor 50 hits floor 49. On impact, those 2 floors fall together with an initial velocity that is less than that of higher floors due to conservation of momentum. Thus the next impact will not be floors 50,49 with floor 48 but rather it will be floor 51 hitting the slower moving 50,49 combo. The 3 floors 51,50,49 then become a unit. The initial velocity of the new 51,50,49 combo will be greater than the velocity of the 50-49 combo just before impact, but still less than that of the floors above (which are still in free fall). http://www.rwgrayprojects.com/synergetics/plates/figs/plate01.html thus: Global Warning, an *anonymous* article in an old issue of *National Review*, the so-called conservative mag of the grotesque Establishment creature, William Buckley, was a sort of benignly-spun expose of the Mont Pelerin Society, the vehicle of British imperialist free trade, free beer free dumb, whose many rightwing affiliate foundations are always in the news. the universally-newspaper-lauded-when- he-died founding president, Mitlon Friedman, used Sir Henry of Kiss.Ass. to conduct their first experiment in Chile, with the help of Augusto Pinochet Dick Nixon.

Re: My Python annoyances
James Stroud [EMAIL PROTECTED] wrote: André wrote: [snipping total repost of André's post] I'm really annoyed at Python - and not for the reasons already mentioned on this list. Everyone know that programming is supposed to be a dark art, nearly impossible to learn. Computer code is supposed to be something impossible to read to the common person and yet reveal their secrets to the initiated - just remember the code displayed in the Matrix... Python takes all of that away. It is just too readable. Even beginners can quickly learn to read code written by experts. To make it even friendlier to beginners, Python uses ugly double underscores both as prefix and suffix on magic methods to be invoked only by more advanced programmers. What's the fun in hiding the complexity so that beginners can stay away from potential problems. And why, oh why, does raw_input() have to go? Here was at least one good example of something that gave a hint (what does raw mean?) at the underlying complexity. Combined with the evil of the hidden eval in the more obvious input(), there was at least a chance to trip beginners into doing something dangerous. Alas, that will no longer be the case... Python does not even make good use of weird symbols like $ and @ and % to define variable types like Perl does. Now, that's a language to learn if you want to be respected. I think that Georg Brandl had it right in his recent proposal: http://mail.python.org/pipermail/python-dev/2007-April/072419.html If not Perl, perhaps Python should be inspired by a language like C++, full of arcane stuff and, thankfully, requiring typing declaration. This dynamic typing thing makes it just too easy to write working programs quickly, especially combined with the ease of use of the interpreter. And this other thing called duck typing is just too flexible to use. No, Python should be more difficult. It should take a full two minutes to compile a Hello World program on a modern computer. Also, this docstring business has to go. Any programmer should, as a rite of passage, have to spend countless hours reading obscure documentation to learn other people's code before finding out what methods can be used and how they should be used. Having to use things like dir and help just makes it too easy. And don't get me started about the absence of curly braces to define blocks of code. What's the fun in making it so darn visually easy to define such blocks of code, removing the possibility of creating subtle bugs due to the misplacement of a curly bracket. No sir, with Python, the structure has to be obvious at a glance - newbies can see it just as well as experts, thereby decreasing the aura surrounding the latter. This is not fair for people that have spent dozens of hours in learning to program using Python! And don't talk to me about functions, classes and methods, not to mention modules. Python makes it too easy to write code in many different styles, trying to please people who like to write only object-oriented code as well as those that follow the more traditional procedural approach. Even functional type people find their way to write code in their preferred method using Python. This is not right. Fortunately, Python has incorporated some newbie-unfriendly features, like metaclasses and, to a lesser extent, decorators which, at last, make use of a special character. There should be more of these, to make Python something more challenging to learn. Programming should be more difficult than this - otherwise, how can programmers be respected by the common folks? --- André I want to complain about the fact that I wrote 200 lines the other day and it worked first time.

Some very early FORTRAN compilers allowed you to redefine integer constants: CALL SET(25,99) WRITE (6,100) 25 100 FORMAT(I6) SUBROUTINE SET(IVAR, INEWVAL) IVAR = INEWVAL would print 99 It was generally agreed by 1970 or so that this was a bad idea, and was taken out of the language. It was still perfectly legal in the Fortran 1977 standard for a compiler to cause this effect, because the Fortran source you quote has *undefined behavior* -- the compiler doesn't have to diagnose this error and can cause any effects as a consequence. The point of Fortran is to let the compiler generate the fastest code it can, NOT to tenderly hold your hand lest scary bugs disturb your blessed and dreamy innocence. If this has changed in the Fortran 1990 standard or later, then I can only say I'm happy I stopped using Fortran heavily before such standards became widespread in commonly available compilers -- by the late '90s, when I was still using _some_ Fortran, it was Fortran '77, as that was the version that was widely available and well optimized. Python is not particularly focused on coddling the programmer lest he or she (horrors!) make a mistake, either; rather, it embodies well 4 of the 5 principles that make up the Spirit of C according to the Preface to C's ISO Standard -- trust the programmer, don't stop the programmer from doing what needs to be done, keep the language small and simple (the 4th one, offer only one way to perform an operation, is not germane here). Making the language more complicated (e.g., with more reserved words) because you _don't_ trust the programmer and badly wants to stop him/her from doing something is not well consistent with these principles. Maybe somebody assigning a value to True or False is a common error, but much of my livelihood over the last 10 years has been about mentoring/coaching programmers in Python, and that's one error I have *NEVER* observed, so I'd need a lot of empirical evidence to convince me it's worth adding two more reserved words to Python's reasonably short list (I feel much the same way about None, by the way). pychecker, pylint, and friends, are a much better way to detect and warn about all sort of anomalies of this kind.

Yes, I admit that it was a very stupid mistake. (Though I'm not even sure that this is what happened. Next time I should probably sleep on it, and try it again the next day, to avoid posting such a stupid question again.) But note that I was using Python interactively (just experimenting with it). It is very unlikely that someone would write things like True == 2 without any additional context in a real program. (Actually it is unlikely that someone would write this in any circumstance in a real program.) But I still think that it is an inconsistency to allow to redefine a _value_ like True or False (not a built-in function that may have been missing in earlier versions). Saying True = 2 is just like saying 3 = 2.
