hi I have 2 lists of numbers,say x=[2,4,3,1] y=[5,9,10,6] I need to create another list containing z=[2*5, 4*9, 3*10, 1*6] ie =[10,36,30,6]I did not want to use numpy or any Array types.I tried to implement this in python .I tried the following z=[] for a,b in zip(x,y): z.append(a*b) This gives me the correct result.Still,Is this the correct way?
If it gives the expected results then it's at least *a* correct way !-)
Or can this be done in a better way?
A list comp comes to mind, as well as using itertools.izip if your lists are a bit on the huge side.
from itertools import izip z = [a * b for a, b in izip(x, y)] -- http://mail.python.org/mailman/listinfo/python-list
