Membership Operators test for membership in a sequence, such as strings, lists, or tuples but in dictionary we can only test for presence of key, not the value.
| Operator | Description | Syntax |
| in | If a sequence with the specified value is present in the object. Returns True. | a in b |
| not in | If a sequence with the specified value is not present in the object. Returns True. | a not in b |

print("g" in a)
print("d" not in a)
Output:
