Announcing Wing IDE 101 for teaching intro programming courses
Hi, We're pleased to announce the first public beta release of Wing IDE 101, a free scaled back edition of Wing IDE that was designed for teaching introductory programming courses. We are releasing Wing IDE 101 to the general public in the hopes that it may help others teach with or learn Python. Wingware also offers educational pricing for Wing IDE Professional, including steep discounts for class room use. If you are interested in teaching Python with Wing IDE, please email [EMAIL PROTECTED] for more information. Key features of Wing IDE 101 include: * Powerful Editor -- Syntax highlighting, goto-definition, navigation menus, error indicators, auto-indent, and keyboard emulation for Visual Studio, VI/Vim, Emacs, and Brief. * Python Shell -- Evaluate files and selections in the integrated Python shell. * Graphical Debugger -- Set breakpoints and view stack and program data. Note that Wing IDE 101 omits auto-completion and most other code intelligence features found in the other Wing IDE products. This was by design, so that students are more conscious of the details of the language and the modules that they are learning about. Wing IDE 101 is available on Windows, Linux, and Mac OS X. It is free for all non-commercial uses and does not require a license code to run. Wing 101 is not, however, open source. The current release is 3.0 beta1 and is available here: http://wingware.com/downloads/wingide-101 General information for beta testers is here: http://wingware.com/wingide/beta More details on Wing 101's features are here: http://wingware.com/wingide-101 http://wingware.com/wingide/features Please direct bug reports and suggestions to [EMAIL PROTECTED] Thanks!

Re: Website data-mining.
Hello, I'm using Python for the first time to make a plug-in for Firefox. The goal of this plug-in is to take the source code from a website and use the metadata and body text for different kinds of analysis. My question is: How can I retrieve data from a website? I'm not even sure if this is possible through Python. Any help? Have a look at http://www.myinterestingfiles.com/2007/03/playboy-germany-ads.html for getting the data and at http://www.crummy.com/software/BeautifulSoup/ for handling it.

You really need to just dig in and start coding. I would recommend Programming Python 3rd Ed. by Lutz if you want something in hard copy. Dive Into Python is a free book that's online that I'm told is very good. Both have good examples, some of which are involved. All the web oriented Python books are a few years old, but the code in them still works, for the most part. Mike Mike, Thanks for your suggestion. I am looking for a python GIS package (without any other GIS backends like mapserver) which can be simply imported into my current python web application. I am not sure if it is available. So far, the close one I found is Python Cartographic Lab. But I can not find any examples for PCL. Anyway, I am still on the way of the deep learning curve for GIS.

Re: How to pass a reference to the current module
Steven D'Aprano wrote: I suggest you're falling for the anti-pattern of Big Design Up Front, and are overly complicating your system just in case it's useful. Why not just _insist_ that main.py and UserDefined1.py must be different modules? You're the application developer, you're allowed to do that. The idea of the module I'm writing is to allow the user to define functions where they want and to create single-file python scripts that can make use of my API. The point of the module is to be beginner friendly, but maybe that is asking too much as user friendliness might be a potentially useful but provably unnecessary attribute. 2. foo is defined in `main` Maybe you should just prohibit that? Do you really want to allow users to call arbitrary code in your main application at arbitrary times and places? It would be the user's main and they would be importing my module. I would like my module to be aware of the contents of the user's module. I thought such a thing would be possible because it seems like something similar is happening in distutils py2app. But in any case, it shouldn't matter. main is the program running -- it has to be, because you can't import it from another program -- so globals()['foo'] will work. Possibility two (even when it is a properly named module) sets the stage for a circular import, but I believe in python this is not entirely worrisome. However, the combination above makes it difficult to pass a reference to the `main` namespace without some sort of introspection. That's what globals() is for. On second thought this might not be horribly bad: FunctionUser.do_something_with(globals(), 'doit', 7) or FunctionUser.do_something_with(UserDefined1.globals(), 'foo', 7) From a beginner-user's perspective (i.e. potential users of my module), it seems a little awkward, but might be more natural on the whole than the alternatives. However, if I had my druthers, I would rather have some way to pass a reference to the current module in the former case and have do_something_with() call globals(). I really like the idea of having the module or its namespace as an optional argument and implicitly using the calling global namespace if its left out. But perhaps this is bad design from an explicit is better than implicit perspective. [foo] param1 = float param2 = 4 [option1] __module__ = 'UserDefined1' __function__ = 'doit' I'm not sure why you need the quotation marks around the module and function names. What else could UserDefined1 be, other than a string? Yes, those were typos. And to be consistent, the whole listing of the configuration file should be (note: 'doit'-do_something_with): [foo] param1 = float param2 = 4 [option1] __module__ = UserDefined1 __function__ = do_something_with param1 = str param2 = 30.0 [doit] param1 = float param2 = float [etc.] With the user's main having the following in it: from UserDefined1 import some_function def foo(): [etc.] def doit(): [etc.] I'm afraid my previous listing of the config file could cause confusion.

Problems with headers in email.message
Hi, python newbie, struggling to learn here. I'm trying to write a
simple program which posts messages to my google group (via email).
I'm using smtplib, email and email.message to build and send a
message, but all the header attributes are appearing in the message
body, so my messages are arriving with loads of junk in the body, no
subject line and only the skinniest of headers. I know I'm doing
something wrong, but I don't know what...

m.set_payload('This is a test email. Please ignore')
s = smtplib.SMTP('smtp.myemail.com')
failed =
s.sendmail('[EMAIL PROTECTED]','[EMAIL PROTECTED]',str(m))
if failed:
print 'Message sending failed.'
else:
print 'Message sent.'
print 'Bye.'
-Snip Here-Snip Here-Snip

Now, I get all the right responses, and the message sends ok. I go and
check my inbox, and the message is there, but the From, To and Subject
lines I created (as well as a preceding blank line and a From nobody
line) are in the message body, followed by the body text.
How do I assign values to the header?
I'd appreciate any help anyone can give me with this.

The Python standard library is probably much bigger than the C standard library, but Kernghan and Richie don't cover it. The complete standard library, plus some Unix-centered stuff is covered in KR. Python compares closely to C++ in the scope of its built-in features. KR is a unique book. I have never seen anything comparable for any language. That's partly because C is so small, though. Also Kernighan is a good technical writer. I'm not sure of Ritchie's contribution, as I haven't read any other books he wrote. The closest Python equivalent is the official docs: http://docs.python.org/ I think the core Python bookshelf is: Learning Python (Lutxz Ascher) and/or Dive Into Python (Pilgrim) for tutorial Python in a Nutshell (Martelli) AND Python Essential Reference (Beazley) for reference The latter two books are not perfect (both indexes are infuriating) but I usually find that I can find what I am looking for in one or the other.

This works nicely when the dimensions of the nested list are small.
It is slow when they are big. Can someone suggest a clever way to
speed it up?
Each use of sortedList.index is O(N) [where N is len(singleList)], and
you have N such uses in the map in the inner function, so this approach
is O(N squared). Neil's suggestion to use bisect replaces the O(N)
.index with an O(log N) search, so the overall performance is O(N log N)
[[and you can't do better than that, big-O wise, because the sort step
is also O(N log N)]].
beginner's advice to use a dictionary is also good and may turn out to
be faster, just because dicts are SO fast in Python -- but you need to
try and measure both alternatives. One way to use a dict (warning,
untested code):
def rankList(singleList):
d = {}
for i, item in reversed(enumerate(sorted(singleList))):
d[item] = i
return [d[item] for item in singleList]
If you find the for-clause too rich in functionality, you can of course
split it up a bit; but note that you do need the 'reversed' to deal with
the corner case of duplicate items (without it, you'd end up with 1s
instead of 0s for the third one of the sublists in your example). If
speed is of the essence you might try to measure what happens if you
replace the returned expression with map(d.__getitem__, singleList), but
I suspect the list comprehension is faster as well as clearer.
Another potential small speedup is to replace the first 3 statements
with just one:
d = dict((item,i) for i,item in reversed(enumerate(sorted(singleList
but THIS density of functionality is a bit above my personal threshold
of comfort (sparse is better than dense:-).
Alex
Thanks for breaking it down so thoroughly. I try the different
recipes and see which gives the best trade offs between readability
and performance. Agreed that dict() approach looks promising.

Even if serving a local page, some kind of web server would be necessary in order to process the request from the submitted form, and execute the Python CGI script. I know you said you can't add anything to the workstation, but you must be able to at least add Python scripts and html files, so perhaps you can get away with adding a self-contained web server? I recommend TinyWeb ( http://www.ritlabs.com/en/products/tinyweb/ ). It's only 53k and supports all the basic webserver functions, including CGI. You can drop TinyWeb in your working directory, start it up with a simple shortcut or batch file, and then have your local HTML form submit to a CGI script processed through TinyWeb. I've used it for a very similar project before, it's so tiny and lightweight that it really doesn't get in the way, and the CGI portion works just fine with Python. If you really can't add anything at all (not even Python packages??), the only other way to do this that I can come up with would be to implement your own simplistic web server in Python that receives the incoming request. Twisted has a CGI-enabled web server in it, and CGIHTTPServer also offers one. However, CGIHTTPServer uses os.fork and is not available on Windows: http://www.python.org/doc/1.5.2p2/lib/module-CGIHTTPServer.html - but you could possibly use it as a starting point. Other than the above the only suggestion I can give would be to search for another way to approach your problem. For instance, using an hta http://msdn2.microsoft.com/en-us/library/ms536496.aspx or using a Tkinter/wxWidgets GUI instead of an html form. -Jay -- http://mail.python.org/mailman/listinfo/python-list

Re: The Modernization of Emacs: keyboard shortcuts pain
The following article a extended version of previous post. A HTML version can be found at http://xahlee.org/emacs/emacs_kb_shortcuts_pain.html --- WHY EMACS'S KEYBOARD SHORTCUTS ARE PAINFUL Xah Lee, 2007-07 A important aspect in designing a keyboard shortcut set, for a application that has intensive, repetitive, prolonged human-machine interaction (such as coding and text editing), is to consider ergonomic principles. Specifically: allocate keyboard shortcuts for the most frequently used commands, and, the top most frequently used commands should have most easily-pressed keystrokes. For example, they should be on the home row. This article shows why Emacs's keyboard shortcut set are the most ergonomically unsound. THE SWAPPING OF CONTROL AND META MODIFIERS Emacs's keyboard shortcuts is very inefficient. The primary cause is because, emacs's keyboard shortcuts are designed with a keyboard that practically has the Ctrl and Alt key positions swapped. Space Cadet keyboard above: The Space-cadet keyboard (Source↗, 2007-07) . The common keyboard used around emacs era in the 1980s are those keyboards from Lisp Machines↗. (see Space-cadet keyboard↗) The keyboard on lisp machines have the Control key right besides the space bar (similar to the position of Alt keys on PC keyboards), and Meta to the left of Control. So, the Control key is right under the thumb, and the Meta is secondary to Control. This is why, the shortcuts for the most used commands in emacs involve the Control key instead of the Meta key. (e.g. The cursor movements: C-p, C-n, C-f, C-b, C-a, C-e, the cut/paste/undo C-w, C-y, C-/, the kill-line C-k, the mark C-SPC, the search C-s.) Lisp Machine's keyboards fell out of use alone with Lisp Machines. Since the 1990s, the IBM PC keyboard↗ (and its decedents) becomes the most popular and is used by more than 99% of personal computers today. The PC keyboard does not have Meta key but have Alt instead, which is practically used as Meta for emacs. The Ctrl and Alt key's position are essentially swapped from the Control and Meta on the Lisp Machine's keyboards. Emacs however, did not change its keyboard shortcut set by switching the commands that are mapped to the Control and Meta keys. This makes emacs keyboard shortcuts very painful, and the frequent need to press the far-away Control key makes the Emacs Pinky syndrome. (Many emacs-using programer celebrities have injured their hands with emacs. (e.g. Richard Stallman↗, Jamie Zawinski↗), and emacs's Ctrl and Meta combinations are most cited as the major turn-off to potential users among programers) THE CHOICE OF KEYS The shortcut's key choices are primarily based on first letter of the commands, not based on key position and finger strength or ease of pressing the key. For example, the single char cursor moving shortcuts (C-p previous-line ↑, C-n next-line ↓, C-b backward-char ←, C-f forward-char →) are scattered around the keyboard with positions that are most difficult to press. (these shortcuts all together accounts for 43% of all commands executed by a keyboard shortcut) Of these, the most frequently used is C-n (next-line), which accounts for 20% of all shortcut calls, but is assigned to the letter n, positioned in the middle of the keyboard, which is one of the most costy key to press. Similarly, the second most used among these is the C-p (previous- line), accounting for 16% of all shortcut command calls, is located in a position above the rigth hand's pinky, also one of the most costy key to press. (Here we assumes the QWERTY keyboard layout. On the Dvorak layout, it is about as bad.) OUTDATED COMMANDS A significant portion of emacs's major shortcuts (those with M-«key» or C-«key») are mapped to commands that are almost never used today. Some of these occupies the most precious space (Home row with Meta: e.g. M-s (center-line), M-j (indent-new-comment-line), M-k (kill- sentence)). Most programer who have used emacs for years never use these commands. For example: digit-argument, M-1 to M-9 negative-argument, M-- move-to-window-line, M-r center-line, M-s transpose-words, M-t tab-to-tab-stop, M-i M-g prefix, M-g indent-new-comment-line, M-j tmm-menubar, M-' zap-to-char, M-z back-to-indentation, M-m tags-loop-continue, M-, find-tag, M-. NO EMPLOYMENT OF THE SHIFT KEY For historical reasons, emacs do not use any keybindings involving the Shift with a letter. (e.g. there's no “meta shift a”, or “control shift a”) This is so because in early computing environment, such key combination cannot be distinguished, due to a practical combination of ASCII↗, Computer terminal↗, telnet↗. Today, however, employing the Shift key as part of a shortcut with other modifiers is common and convenient. For example, on Mac OS X, Undo and Redo are Cmd+Z and Cmd+Shift+Z, Save and Save As are Cmd+S and Cmd+Shift+S. On Mac and Windows, moving to next/previous field/ window/application often use the Shift key for reversing

Yes, but only by accident. It will fail again if you try to do
os.listdir('c:\tmp'). You need to use the right quoting.

Re: Efficient Rank Ordering of Nested Lists
beginner's advice to use a dictionary is also good
and may turn out to be faster, just because dicts are
SO fast in Python -- but you need to try and measure
both alternatives.
One way to use a dict ( warning, untested code ) :
def rank_list( single_list ) :
d = { }
for i , item in reversed( enumerate( sorted( single_list ) ) ) :
d[ item ] = i
return [ d[ item ] for item in single_list ]

also, I would suggest you use CSV format. CSV stands for Comma Seperated
Variable and Excel can load such a sheet directly.
Instead of seperating using ; seperate using , Of course, this provides a
problem when there is a , in a string. Resolution is to quote the string.
Being such, you can just go ahead and quote all strings. So you would want
the output to be:
friendid,Female,23 years old,Los Gatos,United States

Numbers should not be quoted if you wish to treat them as numeric and not

also, I would suggest you use CSV format.
Well, the OP asked for a specific format. One is not
always at liberty to change it.
CSV stands for Comma Seperated
Variable and Excel can load such a sheet directly.
And Excel can load the shown format directly also,
just specify the delimiter.
Instead of seperating using ; seperate using , Of course, this provides a
problem when there is a , in a string.
Which explains the popularity of using tabs as delimiters.
The data deliverable specification I use at work
uses the pipe character | which never appears as data
in this particular application.
Resolution is to quote the string.
Which makes the file bigger and isn't necessary
when tabs and pipes are used as delimiters.
Being such, you can just go ahead and quote all strings. So you would want
the output to be:
friendid,Female,23 years old,Los Gatos,United States
friendid,Male,24 years old,San Francisco, California,United States
Which I would do if I had a specification that
demanded it or was making files for others. For my
own use, I wouldn't bother as it's unnecessary work.
Numbers should not be quoted if you wish to treat them as numeric and not
text.
A good reason not to use quotes at all. Besides which,
Excel can handle that also.

I wanted to implement an UDP protocol in Python. For sending and receiving UDP packets, I chose SocketServer.UDPSocketServer along with the DatagramRequestHandler. It is probably implied, but did not become clear to me just by reading the documentation, that apparently a server is meant to send back a packet for every packet it receives, no matter what. Which in turn means that you can't have servers talk to other servers, because they'd be sending packets back and forth endlessly then. At least, that's what the DatagramRequestHandler is doing. It issues a socket.sendto in its finish() routine. Took me a while to find out where all the empty packets where coming from... Does it make sense at all for an UDP server to do this? Sure, it works for simple protocols that do nothing but query/answer. But it's really useless for anything else. The documentation could be more verbose on this behaviour, in any case. -- You can respond by visiting: https://sourceforge.net/tracker/?func=detailatid=105470aid=1767511group_id=5470 ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
