I'm trying to do a randomised math quiz and I have made it only do one question for times sake:

When I run this the program will repeat itself over an over again, even though I have only called upon a function once.(I understand this is probably very basic and messy but please have patience with me <3)

By the way, `range(0,1)` is just `0`. So you don't need the for loop, you're only executing that part of the code once anyway — Farhan.K, Oct 10 '16 at 12:49
You shoud take a look at [PEP 8](https://www.python.org/dev/peps/pep-0008/). Besides, your functions should return the attempts number (if you actually need it, you are not using `redos` for now) instead of using a global variable. — S. de Melo, Oct 10 '16 at 12:51
`questions = (subtractquestion, additionquestion, divisionquestion, multiplyquestion)` And in the loop: `random.choice(questions)()` — S. de Melo, Oct 10 '16 at 13:03
@Farkan.K It is intentionnal. OP mentions "I have made it only do one question for times sake" meaning that in normal situation it is intended to run the loop more than once (by swapping 0,1 for a bigger range). — jadsq, Oct 10 '16 at 13:03
You want to be careful [comparing floats](http://stackoverflow.com/questions/26091689/python-floating-point-number-comparison) — CAB, Oct 10 '16 at 13:09
Also, get in the habit of using '[if \_\_name__ == '\_\_main__':](http://stackoverflow.com/questions/419163/what-does-if-name-main-do) — CAB, Oct 10 '16 at 13:13
