1. Structures in Python

   Sometimes I miss the C’s plain old struct in Python.

   Of course Python has dictionaries, but I prefer to write a.b over a['b'].

   Here are several ways of doing something akin to a struct in Python.

2. Using gnuplot from Python

   According to my revision control systems (rcs in those days), I’ve been using gnuplot to make graphs since at least 2002. And I’ve got it set up via a custom gnuplotrc to match the style of the TeX documents I often use the graphs in.

6. Extracting data from XML with regular expressions

8. Python bindings for libmagic

   This documents how I installed Python bindings for libmagic.

   There are actually different bindings for libmagic. One set is part of the original distribution. It can be found in /usr/src/contrib/file/python/. But in my opinion it is somewhat cumbersome to use and not very Pythonic.

   The implementation from ahupp/python-magic in Github feels more natural.
