Comparing two objects

Question

Is there any way to check if two objects have the same values, other than to iterate through their attributes and manually compare their values?

Answer 1

To expound on delnan's answer:

_NOTFOUND = object()

class Rational(object):
    def __eq__(self, other):
        for attr in ['numerator', 'denominator']:
            v1, v2 = [getattr(obj, attr, _NOTFOUND) for obj in [self, other]]
            if v1 is _NOTFOUND or v2 is _NOTFOUND:
                return False
            elif v1 != v2:
                return False
        return True
