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

In ascending order you can use:

sorted_data= sorted(non_sorted_data, key=lambda k: (k[1],k[0]))

or in descending order you can use:

sorted_data= sorted(non_sorted_data, key=lambda k: (k[1],k[0]),reverse=True)
