Python Function Returning None Instead of Expected List After Modifying In-Place
I'm converting an old project and I'm sure I'm missing something obvious here, but I'm working with an scenario in my Python function where I'm trying to modify a list in-place, but the function ends up returning `None` instead of the modified list. I'm using Python 3.10 and the function is supposed to append items to a list based on some conditions. Here’s the relevant part of my code: ```python def add_items_to_list(original_list): for i in range(5): if i % 2 == 0: original_list.append(i) return original_list my_list = [] result = add_items_to_list(my_list) print(result) print(my_list) ``` I expected `result` to show `[0, 2, 4]` and `my_list` to have the same content. However, I got `[]` for both the `result` and `my_list`. After debugging, I noticed that my function modifies `original_list` correctly, but for some reason, the return value is not what I expect. I’ve also tried checking if the function is being called correctly, and I've confirmed that it is. I’m not sure why the return value is `None`. I’ve read that Python functions return `None` by default when there is no explicit return statement, but I do have a return statement. Could there be something I'm overlooking? Any insights would be appreciated! Thanks, I really appreciate it! Any pointers in the right direction?
