Python Project 7: Read & Write JSON Files 🔄📄

📌 Problem Statement:

Create a Python script that reads data from a JSON file, manipulates it, and writes the updated data back to a new JSON file.

🧠 What You'll Learn:

• Working with JSON using Python's json module
• Parsing nested structures
• Reading & writing files

✅ Python Code:

import json

Read JSON file
with open("data.json", "r") as f:
    data = json.load(f)
    print("Original Data:")
    print(data)

Modify data (example: add a new key)
data["status"] = "processed"

Write to a new JSON file
with open("updated_data.json", "w") as f:
    json.dump(data, f, indent=4)

print("\nUpdated JSON saved!")

📥 How It Works:

• Loads data.json
• Adds or updates values in the dictionary
• Writes the updated data to updated_data.json

🔧 Try modifying:

– Loop through a list of items
– Extract nested values
– Merge multiple JSON files

💡 Use Cases:

– Handling API responses
– Config file updates
– User data storage
