Intricacies of Aliasing

[snippsat]

id(some_list) always gives you the address of list object in memory,not what the list contain.
Since lists are mutable they create new object in memory every time.

>>> id([])
13622648
>>> id([])
8717336
>>> id([])
13621328

The object integer inside list container is immutable and can point to same place in memory.

>>> x = [1]
>>> y = [1]
>>> id(x) == id(y)
False
>>> # is use id()
>>> x is y
False
>>> # == dos not
>>> x == y
True
>>> # Test integer object inside of list
>>> id(x[0]) == id(y[0])
True
>>> 
>>> help(id)
Help on built-in function id in module builtins:

id(obj, /)
    Return the identity of an object.
    
    This is guaranteed to be unique among simultaneously existing objects.
    (CPython uses the object's memory address.)
