9. Access Only Unique Key Values of a Python Object

Write a Python program to access only unique key value of a Python object.

Sample Solution:-

Python Code:

import json
python_obj = '{"a":  1, "a":  2, "a":  3, "a": 4, "b": 1, "b": 2}'
print("Original Python object:")
print(python_obj)
json_obj = json.loads(python_obj)
print("\nUnique Key in a JSON object:")
print(json_obj) 

Output:

Original Python object:
{"a":  1, "a":  2, "a":  3, "a": 4, "b": 1, "b": 2}

Unique Key in a JSON object:
{'a': 4, 'b': 2}

• Write a Python program to filter a dictionary so that each value appears only once, returning a new dictionary with unique values.
• Write a Python program to use set operations to extract keys from a dictionary whose associated values are unique.
• Write a Python program to implement a function that returns a dictionary containing only the keys with values that occur exactly once.
