commonsguy/cwac-anddown. Another Markdown implementation - this one uses sundown internally and JNI and the NDK to have a fast implementation of Markdown on Android. Worked flawlessly for me with the Nexus.

LuminosoInsight/python-ftfy. A handy little tool that cleans up various inconsistencies in text encodings after something has gone wrong. This is of course no substitute for correct use of encodings in Python, but sometimes you get your input from external sources (or have legacy data from old programs from times when the whole Unicode stuff was not yet so well developed) and have no influence on how the data looks - in that case, this is a very practical little tool.
kmike/marisa-trie. Very practical - there are quite a few things done in Python with Dicts that actually belong in other structures. Especially the prefix search and the search for existing prefixes is practical. And all of this with a C extension also quite fast.
