Python is less like JavaScript in handling the dot operator than I thought

-

>>> def callCallback(cb):
...     cb()
... 
>>> class MyClass(object):
...     def __init__(self, x):
...             self.x = x
...     def f(self):
...             print('x = %s' % (self.x, ))
... 
>>> myObject = MyClass(3)
>>> myObject.f()
x = 3
>>> callCallback(myObject.f)
x = 3
>>> y = myObject.f
>>> y()
x = 3
>>> id(myObject.f)

>>> id(MyClass.f)
