Fun with TextMate and PDB. TextMate bookmarks (against lines in a file) are stored as OS X extended attributes, which can be accessed from Python using the xattr module. Here’s a clever piece of code that uses bookmarks to set breakpoints in the command-line pdb debugger.

Installing PIL on Mac OS X Snow Leopard for use in Google App Engine. PIL installation instructions that actually work... the ’export CC=“gcc -arch i386”’ incantation in particular. Make sure you run setup.py install using the Python version that the App Engine dev tools are using (I ran “sudo /usr/bin/python2.6 setup.py install”).

countdown_to_newyear.py. A quick Python / OS X script I knocked up last night to count in the new year (using the OS X “say” command).

Python on Leopard. readline is finally bundled, so the interactive interpreter works correctly without hunting around for frustratingly elusive add-ons. easy_install is bundled as well.

Python, Mac OS X, and Readline. This worked for me, though you need to already have gcc and svn installed. It’s crap like this that made me switch to Ubuntu on Parallels for most of my Python development.
