Python, List Comprhension Multiplying 2D list by 1D list to each elements

I want to multiply a one dimensional list with a two dimensional list elements. How can I do it with list comprehension?

a = [1,2]
b = [[3,4],[5,6]]

The desired result is

c = [[3,8],[5,12]

>Solution :

You can use nested list comprehension:

c = [ [x * y for x, y in zip(a, row)] for row in b ]
