How to compile Python 1.0 | 685,732 | <p>For some perverse reason, I want to try Python 1.0.. How would I go about compiling it, or rather, what is the earlier version that will compile cleanly with current compilers?</p>
<p>I'm using Mac OS X 10.5, although since it's for nothing more than curiosity (about how the language has changed), compiling in a Li... | 1 | 2009-03-26T13:16:07Z | 688,259 | <p>Going further backwards in time, I pulled the 0.9.1p1 source from alt.sources via Google Groups' archive. That's 18+ year old code!</p>
<p>I made a few changes (documented in README.reconstructed) to get it to compile on my OS 10.4 box. <a href="http://www.dalkescientific.com/writings/diary/archive/2009/03/27/pytho... | 4 | 2009-03-27T02:00:58Z | [

Pythonic ways to use 'else' in a for loop | 685,758 | <p>I have hardly ever noticed a python program that uses else in a for loop.</p>
<p>I recently used it to perform an action based on the loop variable condition while exiting; as it is in the scope.</p>
<p>What is the pythonic way to use an else in a for loop? Are there any notable use cases?</p>

print "else"

if n % divisor == 0:
found = True # <-- update boolean

mysqldb on python 2.6+ (win32) | 685,869 | <p>I am currently using python 2.6 and I would like to use the win32 mysqldb module. Unfortunately it seems it needs the 2.5 version of Python. Is there any way to get rid of this mismatch in the version numbers and install mysqldb with python 2.6?</p>
| 10 | 2009-03-26T13:45:56Z | 686,631 | <p>There are versions of mysqldb for python 2.6, they're just not available on the official site. It took me a while (and unfortunately I lost the link) but you can search google and find people who have compiled and released 2.6 versions of mysqldb for windows x64 and x32.</p>
