Identity Operators

What are Identity Operators

Python Identity operators are used to check if two objects have the same identity or if they refer to the same memory location

Identity Operators in Python

There are two Identity Operators in Python

is operator

is Identity operator checks if two objects refers to the same memory location, then returns True if they do refer to same memory location else returns False

Example: using is operator

  >>> a = 10
  >>> b = a
  >>>
  >>> c = 1200
  >>>
  >>> # the statement below will return True
  >>> a is b
  True
  >>>
  >>> # the statement below will return False
  >>> a is c
  False

is not operator

is not Identity operator exactly does the opposite by checking if two objects do not refer to the same memory location, then returns True if they do not refer to same memory location else returns False

Example: using is not operator

  >>> x = 20
  >>> y = x
  >>>
  >>> z = 12
  >>>
  >>> #
  >>> x is y
  True
  >>>
  >>> #
  >>> y is z
  False
