Answer the following question

It is in python

Consider the following two functions:

def mystery(nested_list): total = 0 for inner in nested_list: for ele in inner: total += ele return total def mystery2(nested_list): total = 0 for i in range(len(nested_list)): for j in range(len(nested_list[i])): _________ return total

----Fill in the blank in mystery2 in a way so that mystery and mystery2 do the same thing (that is, they return the same value for any given nested_list passed in).
