All possible variants of zip in Python

Question

For example, I have a code looks like this:

a = [1, 2]
b = [4, 5]

How can I get something like this:

[(1,4), (1,5), (2,4), (2,5         


        

Answer 1

You want itertools.product:

>>> import itertools
>>> a = [1,2]
>>> b = [4,5]
>>> list(itertools.product(a,b))
[(1, 4), (1, 5), (2, 4), (2, 5)]
