Pickling is a way to serialize Python objects, while non-pickling refers to objects that cannot be pickled.

• Pickling is used to convert Python objects into a byte stream that can be stored or transmitted.

• Non-pickling objects are those that cannot be serialized using the pickle module.

• Examples of non-pickling objects include file objects, network sockets, and database connections.

• To make an object picklable, it must be able to be reduced to a string of bytes and then reconstruc...read more
