What is pickling and unpickling in Python?

Question

Accepted Answer

Pickling is the process of serializing Python objects, while unpickling is the deserialization back to original objects.

Pickling converts a Python object into a byte stream using the `pickle` module.
Unpickling restores the byte stream back into a Python object.
Example of pickling: `import pickle; pickle.dump(obj, file)`.
Example of unpickling: `obj = pickle.load(file)`.
Pickling is useful for saving program state or sending data over a network.

Accepted Answer

Pickle module accepts any Python object and converts it into a string representation and dumps it into a file by using dump function, this process is called pickling. While the process of retrieving original Python objects from the stored string representation is called unpickling.
