These special method names seem to be Python's way of operator
overloading, indeed.
Still, your not defining an operator, your picking or adding behavior
to one already existing.
class A:
def __init__(self,title):
self.title = title
def __add__(self,rhs):
return "%s %s" % (rhs.title, self.title)
if __name__ == "__main__":
mine = A("Hi")
your = A("Ian")
print mine + your
Neverthehow, this may still be what I am looking for. Although, I
could not get this to work:
class A:
def __init__(self,title):
self.title = title
def __cmp__(self,rhs):
return rhs.title == self.title
if __name__ == "__main__":
mine = A("Hi")
your = A("Hi")
print mine == your
Maybe the == inside the method is being overwritten, as well. Or
maybe I have this all wrong.
