Python: Function always returns None

Question

I have some Python code that basically looks like this:

my_start_list = ...

def process ( my_list ):
    #do some stuff

    if len(my_list) > 1:
                


        

Answer 1

You call process recursively but never ignore it's return value when you do. Add a return statement to pass on the return value::

def process ( my_list ):
    #do some stuff

    if len(my_list) > 1:
        return process(my_list)
    else:
        print(my_list)
        return my_list

Now, when len(my_list) > 1 is True, you actually pass on the return value of the recursive call.
