Python: if more than one of three things is true, return false

Question

I\'m writing a django model that allows my site to have coupons.

Coupons can have three types: lifetime account voucher, certain period of months voucher, certain numb

Answer 1

bool is a subclass of int because Python originally lacked bool, using int for Boolean, so:

if self.months + self.dollars + self.lifetime > 1:
    ...

This works because False == 0 and True == 1 are both true.
