Sofia Heisler No More Sad Pandas 

In this excellent talk, Sofia Heisler explains how to optimize Pandas code. There is a striking difference between a naive implementation and an optimized one, a nearly 500x improvement.

She also described two very useful benchmarking functions, timeit, and line_profiler.

I wonder how much of this would apply to “normal” python development? If nothing else, the two benchmarking functions will certainly come in handy in future optimization.
