How to append to list a function output?

[rama27]

Thank you @deanhystad for reply!

My desired output is a list [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]. Of course, I know I can do it by

 list(range(0, 10)) 

, but this is just an example of something more complicated.

When I arrange my example to:

 
def output(n):
    i = n
    for i in range(0, n-1):
        return i
        i +=1

arr = []
arr.append(output(10)) 

I got an a list [0], which is obvious, because the loop ended after return. But how can I rearrange the output() function to be able to append its output to a list arr? Thanks again!
