Answer 2

Python's operator overloading is done by redefining certain special methods in any class. This is explained in the Python language reference.

For example, to overload the addition operator:

>>> class MyClass(object):
...     def __add__(self, x):
...         return '%s plus %s' % (self, x)
... 
>>> obj = MyClass()
>>> obj + 1
'<__main__.MyClass object at 0xb77eff2c> plus 1'

The relevant section in the Python 3 documentation can be seen here.
