In Python, does 'return self' return a copy of the object or a pointer?

Question

Let\'s say I have a class

class A:
    def method(self):
        return self

If method is called, is a pointer to the A

Answer 1

It returns a reference to the object, look at the following example:

class A:
    def method(self):
        return self

a = A()
print id(a.method())
print id(a)
> 36098936
> 36098936

b = a.method()
print id(b)
> 36098936

About the id function (from python docs):

Return the “identity” of an object. This is an integer (or long integer) which is guaranteed to be unique and constant for this object during its lifetime.
