What are the differences between JSON and Pickle?

What are the differences between JSON and Pickle?

JSON (JavaScript Object Notation) is a lightweight data interchange format that's easy for humans to read and write, while Pickle is a Python-specific serialization format that can serialize complex Python objects.

Which one is better for data storage?

It depends on your use case. JSON is more portable and language-agnostic, making it great for web applications, while Pickle is better for Python-specific applications where you need to preserve object state.

Are there any security concerns with using Pickle?

Yes, unpickling data from untrusted sources can lead to arbitrary code execution. It's safer to use JSON for data from unknown origins.

Can I use JSON to store Python objects?

You can, but you'll need to convert Python objects to a JSON-compatible format, as JSON doesn't support all Python data types natively.

What are some common use cases for each?

JSON is commonly used in APIs and web services, while Pickle is often used for saving machine learning models or Python program states.
