Can you name alternatives to the JSON format in Python?

In Python, besides JSON, there are other formats for serialization and data exchange:

• YAML — a more human-readable format, supported by the PyYAML library.
• MessagePack — a binary format, more compact and faster than JSON.
• Pickle — Python's native format for serializing objects, but not suitable for exchange with other languages and unsafe for data from untrusted sources.
• XML — an old but still used format, supported by the standard xml library.
• Protocol Buffers — a binary format from Google, requires schema description, efficient for large volumes of data.

The choice depends on requirements for readability, speed, security, and compatibility.
