Combine Nested For Loops In Python

Suppose I have a nested loop of the form: for i in List1: for j in List2: DoSomething(i,j) Can it be done as follows: for i,j in combine(List1, List2): DoSomething

Solution 1:

You can use itertools.product

import itertools
for i,j in itertools.product(List1, List2):
    DoSomething(i,j)
