But then I get a list of string instead of integers.
You're close. Now that you've initialized the result variable to
[], you can use + just as you're doing. Just

The other problem is you're confusing the variables inside the function

We are close to the solution, keep trying!

first example.
u : [1.0] v: [1,1] result [2.1]

I have been reading your posts and responses. I find myself frustrated
with your lack of understanding of Python fundamentals and the time and
energy others are putting in that seems to help only a little.
I recommend you take a very basic tutorial, and be sure you understand
the basic concep

So it seems that I can't use vectors as a variable in a function.

Write a function add_vectors(u, v) that takes two lists of numbers
I think that u is the name of the new list and v is the number which
represent the number which must be eveluated.
No. It sounds like you don't really understand the basic concepts
behind functions yet
