PEP 8 recommends against this practice. I also recommend against it because it is a fragile programming style (not robust against minor code modifications):
Instead, consider using the functools.total_ordering class decorator to do the work:
@total_ordering
class Student:
def __eq__(self, other):
return ((self.lastname.lower(), self.firstname.lower()) ==
(other.lastname.lower(), other.firstname.lower()))
def __lt__(self, other):
return ((self.lastname.lower(), self.firstname.lower()) <
(other.lastname.lower(), other.firstname.lower()))
