What are the differences between Pickle and JSON?

What are the differences between Pickle and JSON?

Pickle is a Python-specific serialization format, while JSON is a language-independent format. Pickle can serialize complex Python objects, whereas JSON is limited to basic data types.

When should I use Pickle instead of JSON?

Use Pickle when you need to serialize Python objects and maintain their state. Use JSON for data interchange between different languages or when human readability is important.

Are there any security concerns with using Pickle?

Yes, loading Pickle data from untrusted sources can execute arbitrary code, posing security risks. Always validate or sanitize input.

Can JSON handle complex data types?

JSON can handle arrays and objects, but it cannot serialize complex data types like custom classes or functions.

Which one is faster for serialization?

Pickle is generally faster for serializing Python objects, but JSON is more efficient for simple data structures.
