Replacing overloaded functions with closures.

Hi, i am trying, to no avail yet, to take a C#'s overloaded functions skeleton and rewrite it in Python by using closures. I read somewhere on the net (http://dirtsimple.org/2004/12/python-is- not-java.html) that in Python we can reduce code duplication for overloaded functions by using closures.

Subprocess and pipe-fork-exec primitive

Hi, I am working with the subprocess.py module in Python 2.4.4 and I am confused about it's functionality. It uses the standard pipe-fork-exec method to start a subprocess: # create pipes pid = fork() if pid == 0: # child exec(...) # parent status = waitpid(pid, 0

File handle not being released by close

Hi, I'm in the process of writing some code and noticed a strange problem while doing so. I'm working with PythonWin 210 built for Python 2.5. I noticed the problem for the last py file processed by this script, where the concerned tmp file is only actually written to when PythonWin is closed. In
