is,is not operator and in ,not in operator in LIST in Python

Using is, is not, in, and not in Operators in Python List

---

1) is Operator

The is operator compares the memory address of list, tuple, set, or dictionary objects. If both variables refer to the same object/address, it returns True, otherwise False.

x = [1,2,3]
y = [1,2,3]

if x is y:
    print("equall")
else:
    print("not equall")

Output:

not equal

2) is not Operator

The is not operator is the opposite of is. It returns True when two variables have different memory addresses.

---

3) in Operator

The in operator checks whether a value exists in a List, Tuple, Dictionary, or Set.

Example:

x = [1,2,3,4,5]

if 21 in x:
    print("exist")
else:
    print("not exist")
