How can I read and write JSON files in Python?

You can use the json module in Python. To read a JSON file, use json.load(), and to write, use json.dump().

Can you show me a code example for reading a JSON file?

Sure! Here's a simple example:

import json

with open('data.json') as f:
    data = json.load(f)
print(data)

What about writing to a JSON file?

To write to a JSON file, you can do this:

import json

data = {'name': 'John', 'age': 30}
with open('data.json', 'w') as f:
    json.dump(data, f)

Are there any common errors I should be aware of?

Yes, common errors include FileNotFoundError when the file doesn't exist and JSONDecodeError if the JSON is malformed.
