I have two lists:

list1 = [1,2,3] list2 = [4,5,6]

I want to multiply each number in the first list with each number in the second list to get the result:

list3 = [4,5,6,8,10,12,12,15,18]

How do I do this?

  • I tried using zip but only multiplied each element in the first list with one corresponding element in the second list. – Edward Serfontein Oct 27 '21 at 09:49

There could be a more pythonic way to do this but this gets the job done.

lst1 = [1,2,3]
lst2 = [4,5,6]
lst3 = []
for i in lst1:
    for j in lst2:
        lst3.append(i*j)
print(lst3)

Using list comprehension:

print([(l1*l2) for l1 in lst1 for l2 in lst2])
