Python Membership Operators

Python membership operators test for an element’s membership in Python data structures such as a sequence, string, list, or tuple.

The membership operators are as follows:

Python Operator	Description	Example
in	The in operator evaluates to True if it finds a variable in the specified sequence and False otherwise.	x in y, here in results in a 1 if x is a member of sequence y.
not in	The not in operator evaluates to True if it does not find a variable in the specified sequence and False; otherwise	x not in y, here not in results in a 1 if x is not a member of sequence y.
