python - Subtract values in one list from corresponding values in another list

Question

I have two lists:

A = [2, 4, 6, 8, 10]
B = [1, 3, 5, 7, 9]

How do I subtract each value in one list from the corresponding value in the other list and create a list such that:

C = [1, 1, 1, 1, 1]

Thanks.

Answer 1

The easiest way is to use a list comprehension

C = [a - b for a, b in zip(A, B)]

or map():

from operator import sub
C = map(sub, A, B)
