The "discrepancy" is because _they're fundamentally different_:
>>> a = b = [1,2]
>>> c = [1,2]
>>> a is b
True
>>> a is c
False
>>> a == b
True
>>> a == c
True
`is` is used to determine if two names refer to the same object.
`==` is used to determine if they're equivalent in value.
Both have their uses.
