Python - How do i multiply 2 lists

I am trying to multiply and append 2 lists. I can't understand how it works.

xs = [1,2,3,4]
m = 3
t.append(xs[m])
return t

How does ([1,2,3,4] * [3]) = 4?

Performing i[j] indexes the sequence i with the value j. If you want matrix multiplication then you should look at NumPy.

>>> [1, 2, 3, 4][3]
4

An addition to the list multiplication, we cannot multiply two lists. We can multiply list by a number(Integer; -ve will do as well). Doing this you can repeat or replicate your list may times as:

[1, 2, 3, 4] * 3 OR

3 * [1, 2, 3, 4]

will produce

[1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4]
