[BangPypers] python id function

[leela vadlamudi]

Hi,

Python docs says that id function returns the unique id for an object.

>>> id(10)
165936452
>>> a=10
>>> id(a)
165936452
>>> b = int(10)
>>> id(b)
165936452

>>> x = tuple()
>>> y=tuple()
>>> id(x)
-1208311764
>>> id(y)
-1208311764

>>> l = list()
>>> m = list()
>>> id(l)
-1210839956
>>> id(m)
-1210839700

>From the above example, id(mutable_object) returns different ids, but
id(immutable_object) return always the same id. If I try to create new
immutable object, It is just returning the existed object instead of
creating new. How does it internally manages to return the same object?  Why
it is not creating new object if it is immutable?

What about this below case?

>>> id((1,))
-1208770004
>>> id((1,))
-1208770004
>>> a=(1,)
>>> id(a)
-1208745460
>>> id((1,))
-1208759028

Why is id changes here even if it is a tuple(immutable).
