Python: multiplication override
Just add the following to the class definition and you should be good to go:
__rmul__ = __mul__
Implement __rmul__ as well.
class Foo(object):
def __mul__(self, other):
print '__mul__'
return other
def __rmul__(self, other):
print '__rmul__'
return other
x = Foo()
2 * x # __rmul__
x * 2 # __mul__
