Question

Define pickling in Python. Explain serialization and deserialization of Python object.

Answer 1

Pickling or Serialization is the process of converting Python object hierarchy into a byte stream so that it can be written into a file.

Pickling converts an object byte stream in such a way that it can be reconstructed in original from when unpickled or deserialised.

Deserialization or Unpickling is the inverse process of Pickling where a byte stream is converted into an object hierarchy. Unpickling produces the exact replica of the original object.
