Allows me to do that with out any trouble, and also please check whether you
have appropriate permission to the area where you are trying to create the

permissions you can try running python as super user, or user with proper

Printing Barcodes from webapp?
Hello Group: I am in the planning stages of an application that will be accessed over the web, and one of the ideas is to print a barcode that is generated when the user creates a record. The application is to track paperwork/items and uses barcodes to easily identify which paper/item belongs to which record. Is there an easy way to generate barcodes using Python -- considering the application will be printing to a printer at the client's machine? I thought of two ways this could be done; one would be to interface with the printing options of the browser to ensure that margins, headers, footers are setup properly (I have done this before using activex and IE, but with mixed results); the other would be to install some small application at the client machine that would intercept the print jobs and format them properly (taking the printing function away from the browser). Does anyone have any experience or advice? Any links I could read up on to help me find out how to program this? Another way (easier hopefully) to accomplish this? Thanks for any advice. -- http://mail.python.org/mailman/listinfo/python-list
Re: python vs java & eclips
may be emacs can provide code completion (intellicense)
I have not used it so far so can't say.
but the main reason I use eclipse is for the above feature.
and yes indentation happens in eclipse python-mode so that is not a
major feature eclipse offers any way.
syntax highlighting is a very common feature again.
so if there is an editor which will give me auto code completion, I
will happily give up using eclipse.
by the way, there is one problem I am finding with eclipse and py dev.
the following snippad of code is a mesterious problem.
name = raw_input("please identify your self ")
if name == "tom":
print "hello and welcome"
else:
print "I don't know you"
just run this script and you will find that you always get "I don't
know you", even if you entered tom.
I then figured out that length of name actually comes to 4 even when I
entered tom. that's why it always goes in the else claws.
but when I ran the same script from a command promt the length of name
returned 3 when tom was entered and the code worked fine.
I can't understand why is this happening? why is eclipse putting an
extra character in the name variable?

Possible to assure no "cyclic"/"uncollectible" memory leaks?
I've been doing a lot of searching on the topic of one of Python's more disturbing issues (at least to me): the fact that if a __del__ finalizer is defined and a cyclic (circular) reference is made, the garbage collector cannot clean it up. First of all, it seems that it's best to avoid using __del__. So far, I have never used it in my Python programming. So I am safe there. Or am I? Also, to my knowledge, I have never created a cyclic reference, but we do not typically create bugs intentionally either (and there are certainly times when it is an OK thing to do). Still, it's not comforting to know that it is possible to create a situation that would create a memory leak using a language that is supposed to relieve us of that worry. I understand the problem, but it would be nice to know that as a programmer, I could be assured that Python would always deal with memory management and that memory leaks were not something I had to think about. So here's a question: if I write Python software and never use __del__, can I guarantee that there is no way to create a memory leak? What about system libraries - do any of them use __del__, and if so, are they written in such a way that it is not possible to create a cyclic reference?

temp bat is

am sure the readlines code is crashing it. Because I have moved it
befour the code that is reading a line at a time and it would not even
write the second zero byte file. The comment line is an old line that
I did not update when I made changes. The code that calls it was

Consider the possibility that fromline >= toline (which may be caused
by either or both not being of a numerical type).
Did you mean range(fromline, toline + 1) ?
do this:
print repr(fromline), type(fromline)
print repr(toline), type(toline)
BTW, print is a *statement*, not a function!

converting dict to object
If I have a dictionary such as:
d = {'a' : 1, 'b' : 2}
is there a way to convert it into an object o, such as:
o.a = 1
o.b = 2
thanks

Formatting the string for a very large array can take a fair bit of time, often much more than the computation that generated it. This has been a long-standing frustration of many Numeric users. At the interactive prompt, if the statement you just entered is taking a long time to execute and you Ctrl-C, odds are, the traceback points you right in the middle of array2string(), not anything in the actual computation itself. Since the interactive prompt prints things out without the user explicitly asking for it, it's not enough simply to have two functions available. numarray set the default to summarize, and numpy kept numarray's choice. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco -- http://mail.python.org/mailman/listinfo/python-list

Do you mean to say that the dimension to pursue truth and freedom from deception lack for people using TeX? or they must not be informed of it?

If I am making a guess based on the sample space I have seen in "elite" universities, most jews are fervent Zionists even if they are atheists. I would really like to discuss with some university professors (especially jewish - almost always zionist) what they think of Neturei Karta, and the free book that is there, Min Ha Mitzer, (From the depths) about the role of zionists in abetting the slaughter of the Jews, nay, in fervently provoking Hitler or someone in that very direction.

Fun with with
Occasionally I find myself wanting a block that I can break out of at arbitrary depth--like java's named break statements. Exceptions can obviously be used for this, but it doesn't always look nice. The with statement can be used to whip up something quite usable: class ExitBlock(object): """ A context manager that can be broken out of at an arbitrary depth, using .exit() """ def __init__(self): class UniqueException(BaseException): pass self.breakExc = UniqueException def exit(self): raise self.breakExc() def __enter__(self): return self def __exit__(self, t, v, tb): return t is self.breakExc Now the most important thing here is that each exit block creates a unique exception type. If you have philosophical issues with creates unboundedly many type objects, you can use unique instances too. This allows named break-out-able blocks: with ExitBlock() as ex1: with ExitBlock() as ex2: with ExitBlock() as ex3: while True: ex2.exit() print 'not displayed' print 'execution proceeds here from ex2.exit()' while True: for x in xrange(sys.maxint): while True: ex1.exit() print 'not displayed' print 'execution proceeds here from ex1.exit()' The only danger is bare except (or except BaseException) inside the block. -Mike -- http://mail.python.org/mailman/listinfo/python-list

Re: route planning
It's not really what you're after, but I hope it might give some ideas (useful or not, I don't know). How about considering a vertex as a point in space (most libraries will allow you to decorate a vertex with additonal information), then creating an edge between vertices, which will be your 'path'. You can then decorate the edge with information such as distance/maximum speed etc... Then all you need to do is use an A* path algorithm or shortest path search to get the shortest / most efficient route You might need a custom visitor to suit the 'weight'/'score' of how efficient the path is. I know this probably isn't of much help, but I hope it comes in useful; I've only ever used Boost.Graph (which is C++, but I believe it has a Python binding) and that was for something else -- although I do recall it had examples involving Kevin Bacon and dependency tracking etc... so a good old Google might do you some good -- ie, it's not completely related, but it might give you a few extra things to search on...

Global variables are > global to the threads. That is somewhat misleading. _All_ variables accessible from two threads are shared. This includes globals, but also object attributes and even local variables (you could create a closure to share a local among threads). The only reason locals appear "thread-local" is that locals are "invokation-local" in that they are different bindings every time a function is executed, and generally a single invokation of a function is confined to a single thread. Another way to share local variables is to create a generator, and call .next() in two different threads... the local variables are simulatneously modifiable by both threads.

"common_var" is a local variable to fun_basket, hence it independent among invokations of fun_basket. "def" is a statement that creates a function when it is executed. If you execute the same def statement twice, two different functions are created. Running fun_basket twice creates four closures, and the first two have no relation to the second two. The two sets close over different cell variables. If you want to share data between function invokation, you need an object which persists between calls. You can use a global variable, or a default argument. But since the value is shared everytime the function is called, I don't see the value in using a closure. I don't know lisp very well, but in my mind the whole point of closures is that you can reference a different unique cell each time. -MIke -- http://mail.python.org/mailman/listinfo/python-list

Two calls to fun_basket, two different common_var's, two f1's and two f2's. Each f1/f2 pair have access to a different common_var, so it's working as expected.

What are python closures realy like?
Hi, while writing my last program I came upon the problem of accessing a common local variable by a bunch of functions. I wanted to have a function which would, depending on some argument, return other functions all having access to the same variable. An OO approach would do but why not try out closures... So here is a simplified example of the idea: def fun_basket(f): common_var = [0] def f1(): print common_var[0] common_var[0]=1 def f2(): print common_var[0] common_var[0]=2 if f == 1: return f1 if f == 2: return f2 If you call f1 and f2 from the inside of fun_basket, they behave as expected, so common_var[0] is modified by whatever function operates on it.

Re: detecting that a SQL db is running
I think the main point is that your Python code should be written in such a way that when you attempt to connect to your local MSDE it will timeout correctly instead of hanging. Do you have a loop somewhere that just keeps retrying the connection instead of giving up at some point? Here are a couple of links to bits o code, that you can use to see whats running on your local machine. http://blog.dowski.com/2003/12/20/getting-at-processes-with-python-and-wmi/ http://mail.python.org/pipermail/python-win32/2001-November/000155.html Search the resulting lists for whatever name MSDE is supposed to run as. -Josh On 12/1/06, bill ramsay <[EMAIL PROTECTED]> wrote: Dennis none of this matters, all i am trying to find out is whether or not the local MSDE is actually running.

They object that the pentagon was not hit by a plane and FBI confiscated all the pentagon videos. Furthermore, they have shown by producing a side by side video of Osama that his confession video is a fake, and they call it a synthetic terror. Please visit their sites to debunk their spins: www.scholarsfor911truth.org www.journalof911studies.org http://www.journalof911studies.com/JonesAnswersQuestionsWorldTradeCenter.pdf They are using videos to make a spin in the tradition of Edward L Bernays (Freud's Nephew, see wikipedia on him, and watch the video on how he broke the taboo and convinced women to smoke.).

A good point. Adding checking for "*" would make it rather ugly, as "*"
is special only inside a conversion specifier.

Hmmm ... I hadn't seen that before either. I would have said if shown
that input that I could have put in an error check that pending was not
true at the end of the loop, but was relying instead on an exception
from the formatting operator.
Even better: >>> "%-42%" % ()
'% '

Before gentle readers consider nominating the Python core dev team to
thedailyWTF.com, they might wish to:
(1) read the Python documentation
(http://docs.python.org/lib/typesseq-strings.html)
[it is not a simple escape mechanism; the second % is a "conversion
type"]
(2) compare those docs carefully with K&R v2 section B1.2 Formatted
Output (pp 243-245)
(3) note that not everything that emanated from Murray Hill NJ obeyed
the Law of Least Astonishment

Security Descriptor and CoInitializeSecurity
I'd like to call pythoncom.CoInitializeSecurity with a PySecurityDescriptor object to set the process-wide security values. But I'm not able to find a way to let the code go through. I have read MSDN and searched web, I've not been able to find answer. I cooked a security descriptor like this (assume aces is a tuple of tuple (access, sid) : sd = win32security.SECURITY_DESCRIPTOR() sd.Initialize() sd.SetSecurityDescriptorOwner(sid_owner, False) sd.SetSecurityDescriptorGroup(sid_group, False) # create DACL dacl = win32security.ACL() dacl.Initialize() for (access, acc_sid) in aces: # Add ACE which is access and SID dacl.AddAccessAllowedAce(win32security.ACL_REVISION, access, isinstance(acc_sid, (unicode, str)) and win32security.ConvertStringSidToSid(acc_sid) or acc_sid) sd.SetDacl(True, dacl, False) # SetSecurityDescriptorDacl print sd.IsSelfRelative()# result is 1 The sd is a self relative one. >From MSDN, after calling InitializeSecurityDescriptor, the sd is absolute sd, and CoInitializeSecurity needs absolute sd.

Re: python vs java & eclipse

Eclipse may be quite a technical achievement, but I found it irritating. Aside from the misuse of screen real-estate, I found that typing two characters and having what seemed like half my source file underlined in red, with multiple messages telling me that I had yet to define or import something or other when what I was about to do was to write the declaration, all conspired to make me want to scream, "WTF do you think I was going to type in about five seconds time? Work it out and autocomplete it if you're so damned clever!" So, Eclipse certainly has its share of detractors, too. ;-) [...] > That said, the code completion for Python is still in its early stages. > There is a lot of room for improvement, even for a dynamic language. Agreed. I don't believe in endless refactoring, and I think that's frequently a symptom of using an overly inflexible statically typed language (where it's more like "Refactoring" - the big R symbolising the seriousness and heavy lifting involved), but there are often times when I've wondered whether something could alert me to obvious breakage, especially after fairly big changes, acting possibly within the editing environment. I suppose pylint and similar tools have been working towards that goal, but I often wonder about producing something more subtle: something which is more clever than looking at modules and globals, and yet doesn't nag you continously about things which you'll discover almost immediately anyway.

It was actually developed for being a Java IDE but (as far as I know) people were liking it so much, so they decided to make it expandable (and PyDev is actually a good thing, it supports PyLint and PyChecker, manages the python path when new modules are added, but can be improved (as can everything :-) )).

Not if this is all you are doing. A variable A in script1.py and a variable A in script2.py are completely different, even when running in the same thread. But if you're running script1.py and script2.py by calling execfile or exec and you pass the same dictionary as the globals argument to execfile, then the two scripts would share the global namespace.
