Recursive Functions not return [duplicate]

Question

I'm playing with recursive functions and I'm not figure out why the function is not return if the list is empty ([]) even if the print function before the return is executed.

def go(mylist):
if not mylist:
    print('Empty list')
    return 'List Empty'
else:
    print(mylist)
    mylist.pop()
    go(mylist)

print(go([1, 2, 3, 4, 5]))

I get return 'None' because a function without a a return always return 'None'

You have to return the value that you received from the recursive call:

return go(mylist)
