Raymond Hettinger：把代码改写成地道优雅的 Python（PyCon 2013）

Raymond Hettinger's PyCon 2013 talk on transforming code into idiomatic Python through a series of before-and-after refactorings. It shows how to use iterators, dictionaries, named tuples and other language features well.

Why HN likes it: HN treats it as a must-watch classic for writing Pythonic code, though somewhat dated for modern Python.

“the excellent talk "Transforming Code into Beautiful, Idiomatic Python".”
