I recommend PyToolz, "set of utility functions for iterators, functions, and dictionaries": https://github.com/pytoolz/toolz https://github.com/pytoolz/toolz The functions in PyToolz are short, well tested and idiomatic Python (thought the functional programming paradigm they support is not quite so idiomatic). I recommend starting with the excellent documentation: http://toolz.readthedocs.org/en/latest/ http://toolz.readthedocs.org/en/latest/ In particular, the API docs have links to the source code for each function: http://toolz.readthedocs.org/en/latest/api.html http://toolz.readthedocs.org/en/latest/api.html
