I'm writing a filter and would like to be able to do what the Linux 'file' command does, i.e. look at a couple of bytes to see what kind of data I'm dealing with, the branch based on the type. I scanned the python library and couldn't find anything that seemed to approximate this. I know I could do os.popen and call the file command then...

Hi All, I need some help, whe trying to run some gtk examples, show below messages: Traceback (most recent call last): File "D:\Downloads\python\test\pygtk\examples\pygtk-demo\demos\stock_browser.py", line 216, in -toplevel- main() File "D:\Downloads\python\test\pygtk\examples\pygtk-demo\demos\stock_browser.py", line 160, in main

I was recently surprised, and quite shocked in fact, to find that Python treats negative indices into sequence types as if they were mod(length-of-sequence), at least up to -len(seq). This fact is *deeply* buried in the docs, and is not at all intuitive. One of the big advantages of a high-level language such as Python is the ability to...

Hi there, Just wanted to share a frustrating programming bug that, when I figured it out, made me gasp, and then laugh. In one of my programs I wrote... c = max(a,b) ....and I was getting the most annoying, frustrating error message:

Hi everybody I want to recompile the DISLIN graphics module for Python under Linux, because I think it is one of the best graphics libraries at present. The included module was for version 2.0 and I want it for 2.2 or maybe 2.3. The problem is, that I use the small make_py script which only calls the gcc compiler CC="gcc -fPIC -c -O"...

Hello, I heard that is possible to replace %(word) in a string with a dictionary containing { "word" : "replaced word" } with a function or a builtin from the python library. For example with the string: "hello, %(word1) %(word2) !" and the dictionary: {"word1" : "python", "word2" : "lovers"} the final string would be: "hello python...

I was just writing some code which did date/time manipulations, and I found that the Python 2.3 datetime module does not supply a number of fairly basic functions. I understand the reasoning (the datetime module provides a set of datatypes, and doesn't attempt to get into the murky waters of date algorithms) but as these things can be quite...

Hi, I have a list that consists of lists. E.g. T=, , ] Is there a way to address the a specific component in the "inner" list directly? E.g. right now I want to get the second value of the first list. Unfortunately I have to save it to a variable first and then read it. a = T print a

Hello All, I have been seeing this term "duck typing" for quite sometime now. It will be nice if one of us can give an example in Python demonstrating duck typing and/or link to some Python references. Regards, Srijit

When I pass a function as an arg, like for map(...), how do I pass args to use for that function? If I have a function like this: def pretty_format(f, fmt='%0.3f'): return fmt % f I want to use it with map() like this:

I'm writing a class definition in python with some array atributes from Numeric 2.0. I'm using UserArray, UserList, to subclass my classes. But some of the methods I need to write in C mainly because of computing speed. I need to pass to those C functions array and lists objects that the C functions can access their contained values like...

Hi Everyone, I'm starting learning python about 2 weeks, and still have difficulties to create GUI based application because I never learn about classes and other OOP things. Does anyone knows how to create text console application like clipper using python. Thanks,

A couple of months ago, I posted a call for volunteers on C.L.PY for our demo voting system development project (open source Python on SourceForge). I am very pleased with the result so far. We have some excellent developers to go along with some top notch experts in voting technology we have on board. David Mertz has taken the Development...

Hi- I want to make a list of mx.DateTime objects that cover all the monthly intervals between two points. For example: >>> import mx.DateTime >>> nov1999 = mx.DateTime.Date(1999, 11) >>> mar2003 = mx.DateTime.Date(2003, 3) >>> alldates = mk_list(startdate=nov1999, enddate=mar2003)

Well, it seems there are groups of python audio interface libraries out there. One problem. I can't tell if any of them support multiple sound cards. I'm working on a project that will require me to access and record from more than one soundcard. Does anyone know of a Python wrapper that allows this? I know Alsa allows multiple sound...

I am building extension modules for Python 2.3 under Windows using MS Visual Studio .Net 2003. In the debug build, there is a pragma statement in <pyconfig.h> that causes a link to the lib python23_d.lib This library does not exist. Am I missing something or is the installation missing something?

I've had a production system running for a long time that uses xmlrpclib with timeoutsocket, and with my recent upgrade to 2.3 it's no longer able to use xmlrpclib with the xmlrpc servers I communicate with. I can call remote procedures still, but as soon as I import timeoutsocket and the old socket switcharoo is done it's over. To add to...
