How to combine elements from two lists into a third?

Question

I have two lists a and b:

a  =   [3,    6,   8,   65,   3]
b  =   [34,   2,   5,   3,    5]

c gets [3/34, 6/2, 8/5, 65/3, 3/5]
         


        

Answer 1

Use zip and a list comprehension:

>>> a = [3,6,8,65,3]
>>> b = [34,2,5,3,5]
>>> [(x*1.0)/y for x, y in zip(a, b)]
[0.08823529411764706, 3.0, 1.6, 21.666666666666668, 0.6]
