Python List - “reserving” space ( ~ resizing)

Question

I am given a list l and I want to do assignment:

l[index] = val

But there might be a case when the list is too small.

Answer 1

Try this:

def ResizeList(some_list, length, null_item = None): 
    return some_list + [null_item 
                        for item in range(length - len(lst))]
