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 oth

Answer 1

Since you appear to be an engineering student, you'll probably want to get familiar with numpy. If you've got it installed, you can do

>>> import numpy as np
>>> a = np.array([2,4,6,8])
>>> b = np.array([1,3,5,7])
>>> c = a-b
>>> print c
[1 1 1 1]
