If you want to get to the end of the program easily, there are two ways I've found:First, you could wrap your entire program into a function, and return from the function when you want to exit.Second, you could put your entire program into a try except clause and raise a custom Stop exception: Alternatively, you could just raise an error like:raise Exception('Stop program')however this will create a traceback, which mightn't look pretty :/.
