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

You can do this using list comprehension (element by element):

div = [ai/bi for ai,bi in zip(a,b)]

Note that if you want float division, you need to specify this (or make the original values floats):

fdiv = [float(ai)/bi for ai,bi in zip(a,b)]
