Just like every other object:

>>> class Example(object): pass
...
>>> e = Example()
>>> e.__str__ is e.__str__
False

Python creates a new bound method object every time. A bound method
object is a callable object that keeps a strong reference to the
function, class and object. The bound method object adds the object as
first argument to the function (aka 'self').
