Are you trying to break the loop when you do not receive more items in usernames? You can do that with if len(usernames == 0): break before the for loop.

If you want to test if there are no new items in usernames, you can do either of the following:

if all(user in user_list for user in usernames): break

if set(usernames).issubset(user_list): break

    for each in usernames:
        user_list.append(each)
        working = True
