Why would you use the return statement in Python?

Question

what will happen if we don't use return in function definations

Answer 1

even if not programmed your function will return None. That is ok, but good style is to return smthng like "done", True, "OK" or any other. It will really helpful during debug. With return you can easily check if func did everything right (if myfunc() == True), without it you should check function work totally manually.
