Pandas is some probably very nice and clever Cython wrapped up in disastrous Python. As someone says below, doing anything requires constant reference to the docs, unless you did it yesterday. The semantics given originally to square bracket indexing have unacceptable edge cases with weird fallbacks, and instead of fixing it a bunch of other strange indexing syntaxes have been added on (but any Python programmer will use square brackets first). It's basically a distinct language (and a powerful one if you use it regularly).
