Asking for Help

The most efficient way of getting help is via the various mailing lists and newsgroups, particularly the comp.lang.python newsgroup.

See the Community page for a selection of related resources.

For those of you willing to wait, and to add to the archive of problems (and solutions), enter your question in the list below. For longer questions, consider adding a new page using the button just below: write a short version of the question in the box - this will be the page name - and then write the actual question or problem description in the page editor that appears after pressing the button.

The page will be automatically added to the longer questions section below.


  • How (aside from reading gobs and gobs of source code) can I find out the asymptotic time behaviour of various primitive Python operations? For example, for list xs, does xs.append(x) take amortized O(1) time or O(n) time?
  • ssl-1.14.tar.gz exists and supposedly works with Python 2.5x. Assuming I have Visual Studio .NET 2003 available on my box, how do I build the package for Windows. It currently complains about a series of openssl *.h files that aren't available. I can drag in openssl for www.openssl.org, but which version, if that is applicable, and how do I connect the two either in a directory structure or appropriate configuration files?
  • I'm working with embedding Python into my applications. However, the Py_Initialize() is producing an " 'import site' failed " message on non-dev computers. I was wondering if there is a way to fix this or is it just a bug with Python? Thank you.
  • I'm trying to run the IDLE but it wont go on. i have an R52 leptop with ibm-tools installed (there is ver 2.2 there but i changed it so it wont ebe the default one). im trying to run ver 2.6. Thank
  • I'm new to python and I am just working with the idle-shell. How can I write a script without having python executing orders immediately after I type them into the shell? Follow-Up question: Having written the script, how do I run it in the interpreter?
  • I just installed MacPython. Unfortunately it doesn't seem to include the CoreGraphics-Python Module. Where ist my old system python? How can I uninstall MacPython?

  • Is there any way to get the environment from a subprocess.Popen created by python? In other words, if the new process updates it's environment, is it possible to get access to the modifications. For example In my case I'm executing MS Visual Studio's vsvars32.bat file and would like to access the modified PATH environment variable.
  • Is there any way to determine if the C implementation under my Python uses IEEE 754 for floating point numbers? If yes, what is it?
  • I am trying to run Python script in ABAQUS, but there is a error "Import Error: No Module named " Tkinter"". So how can I handle the problem? Thanks
  • Why do I call constructor of Cmd class in my Cmd subclass __init__ method?

  • When I import Tkinter, Python exits. Why?

  • I am new at python, I have python 2.5 and every time i open the shell python resets my moniter to 800x600. How do I keep python from messing with my monitor settings? -Travis
