How do I use the max function in Python?

Question

num = request.GET.get("num",20)

By default, the num is 20. But, if the user passes in 100, how can I set num to 50? (the max that I allow?)

If you want to trim down a number, you should use min rather than max. — Bolo

If you're having trouble with max, then you're not ready to be using an ORM. (You're a bit of an enigma: this is a very novice question for someone who's asked over 800 questions...) — Glenn Maynard

Just add one more line:

num = int(request.GET.get("num", 20))
if num > 50:
    num = 50

Or, if you want to use min you could write:

# "num" parameter assumed to be convertable to an `int`
num = min(int(request.GET.get("num", 20)), 50)

Actually, you should use min rather than max:

num = int(request.GET.get("num", 20))
num = min(num, 50)

Funny how this is subtly broken: min("100", 50) == 50 == min("15", 50).
