Hi, I'm reading the Python Reference Manual in order to gain a better understanding of Python under the hood.
On the last paragraph of 3.1, there is a statement on immutable and mutable types as such: <paraphrase> Depending on implementation, for immutable types, operations that compute new values may or may not actually return a reference to any existing object with the same type and value, while for mutable objects this is (strictly)? not allowed. </paraphrase> Using the example given in 3.1, how do I verify that this is true pertaining to immutable types? Below is my understanding on verifying the above statement: >>> a = 1 >>> b = 1 >>> a is b True >>> id(a) 10901000 >>> id(b) 10901000 Is this correct?
