repeat statement(s) until( condition ) Notice that the conditional expression appears at the end of the loop, so the statement(s) in the loop execute(s) once before the condition is tested.If the condition is false, the flow of control jumps back up to do, and the statement(s) in ...

-> False or None will result True for stop_flag, we'll have to document that return True will keep the loop running. Thenotkeyword is intentional to make default None return a boolean in stop_flag. then check for stop_flag in while statement. This way we can offer the user a way to...
