The == operator compares the values of both the operands and checks for value equality. Whereas is operator checks whether both the operands ask an equivalent object or not.<\/p>\n

  • Output of the primary if condition is \u201cTrue\u201d as both list 1 and list 2 are empty lists.<\/li>\n
  • Second if condition shows \u201cFalse\u201d because two empty lists are at different memory locations. Hence list 1 and list 2 ask different objects. we will check it with id () function in python which returns the \u201cidentity\u201d of an object.<\/li>\n
  • Output of the third if condition is \u201cTrue\u201d as both list 1 and list 3 are pointing to an equivalent object.<\/li>\n<\/ul>\n
