Here is some quality code Alex Martelli posted on comp.lang.python;
self.data = 
self.first = 0
self.first += 1
if self.first > len(self.data)/2:
self.data = self.data[self.first:]
self.first = 0
def append(self, value):
I'm posting it here as a mental note to myself to use this class whenever I need a first in, first out stack.

Debian Configuration Woes
In the words of Victor Meldrew - "I don't believe it".
I thought I understood this technology stuff. I've managed to install Debian on Bobo's old laptop (a Thinkpad 390E for the technical). All went swimmingly well (eventually). Now I have a stable system which I can boot up and log onto. When I go to do some actual work I discover that the tools I want to use (python, wxGTK, wxPython) are either not present or terribly out of date. "No problem" I think to myself, this was the reason I chose Debian, as it has this wonderful package structure to help me seamlessly upgrade. With just a few key strokes I can get the latest version of any module on the system and know that it will work. Beautiful.
Well, two days and innumerable swear words later and I am no better off. I have traced the source of my frustration though. The Debian package utilities (dpkg, apt-get and dselect) all rely on a configuration file (/etc/apt/sources.list if you must know) and the contents of mine is wrong. I know it is wrong because the package utilities all tell me so. What they don't tell me, and what I can't find anywhere on the web or in the manuals, is how to fix it. Good grief. I shall be writing a stern e-mail, once I have solved my problem (and I'll put the solution up here as well).
