NumPy / SciPy / Pandas Cheat Sheet From quandl.
Useful but also an illustration of the tension between a true cheatsheet (one page, tiny print) and edging towards a legible but multi-page booklet.
I suspect the greatest benefit of a “cheatsheet” accrues to its author. The chores of selecting, typing and correcting being repetition that leads to memorization of the material.
I first saw this in a tweet by Kirk Borne.
