Mapping a nested list with List Comprehension in Python?

Question

I have the following code which I use to map a nested list in Python to produce a list with the same structure.

>>> nested_list = [[\'Hello\', \'Wo         


        

Answer 1

Remember the Zen of Python:

There is generally more than one -- and probably several -- obvious ways to do it.**

** Note: Edited for accuracy.

Anyway, I prefer map.

from functools import partial
nested_list = map( partial(map, str.upper), nested_list )
