Python 3 - Membership Operators Example
Python’s membership operators test for membership in a sequence, such as strings, lists, or tuples. There are two membership operators as explained below −
| Operator | Description | Example |
|---|---|---|
| in | 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 | Evaluates to true if it does not finds 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. |
Example
#!/usr/bin/python3
a = 10
b = 20
list = [1, 2, 3, 4, 5 ]
if ( a in list ):
print ("Line 1 - a is available in the given list")
else:
print ("Line 1 - a is not available in the given list")
if ( b not in list ):
print ("Line 2 - b is not available in the given list")
else:
print ("Line 2 - b is available in the given list")
c = b/a
if ( c in list ):
print ("Line 3 - a is available in the given list")
else:
print ("Line 3 - a is not available in the given list")
Output
When you execute the above program it produces the following result −
Line 1 - a is not available in the given list Line 2 - b is not available in the given list Line 3 - a is available in the given list
