4. Convert Python Dictionary (Sorted by Key) to JSON Data

Write a Python program to convert Python dictionary object (sort by key) to JSON data. Print the object members with indent level 4.

Sample Solution:-

Python Code:

import json
j_str = {'4': 5, '6': 7, '1': 3, '2': 4}
print("Original String:")
print(j_str)
print("\nJSON data:")
print(json.dumps(j_str, sort_keys=True, indent=4))

Output:

Original String:
{'4': 5, '6': 7, '1': 3, '2': 4}

JSON data:
{
    "1": 3,
    "2": 4,
    "4": 5,
    "6": 7
}
