How do I multiply lists together using a function?

Question

how do I multiply lists together in python using a function? This is what I have:

    list = [1, 2, 3, 4]
    def list_multiplication(list, value):
                  


        

Answer 1

You can use a list comprehension:

>>> t = [1, 2, 3, 4]
>>> [i**2 for i in t]
[1, 4, 9, 16]

Note that 1*1, 2*2, etc is the same as squaring the number.

If you need to multiply two lists, consider zip():

>>> L1 = [1, 2, 3, 4]
>>> L2 = [1, 2, 3, 4]
>>> [i*j for i, j in zip(L1, L2)]
[1, 4, 9, 16]
