How to Parse and Modify a JSON File in Python?

To parse and modify a JSON file in Python, you can use the built-in json module.

Here’s an example of how to load a JSON file, modify it, and save it back to a file:

import json

# Load the JSON file
with open('example.json', 'r') as f:
    data = json.load(f)

# Modify the data
data['name'] = 'John Doe'
data['age'] = 30

# Save the modified data back to the file
with open('example.json', 'w') as f:
    json.dump(data, f)

In this example, we first load the JSON file example.json using the json.load() method. We then modify the name and age keys in the data dictionary. Finally, we save the modified data back to the same file using the json.dump() method.
