Sorting a Python list by two fields

Question

I have the following list created from a sorted csv

list1 = sorted(csv1, key=operator.itemgetter(1))

I would actually like to sort the list

Answer 1

No need to import anything when using lambda functions.
The following sorts list by the first element, then by the second element.

sorted(list, key=lambda x: (x[0], -x[1]))
