String serialization is the process of writing a state of object into a byte stream. In python, the “pickle” library is used for enabling serialization. This module includes a powerful algorithm for serializing and de-serializing a Python object structure. “Pickling” is the process of converting Python object hierarchy into byte stream and “unpickling” is the reverse procedure.

The demonstration of the pickle module is as follows −

import pickle

#Here''s an example dict
grades = { ''Alice'': 89, ''Bob'': 72, ''Charles'': 87 }

#Use dumps to convert the object to a serialized string
serial_grades = pickle.dumps( grades )
print(serial_grades)

#Use loads to de-serialize an object
received_grades = pickle.loads( serial_grades )
print(received_grades)

Output

The above program generates the following output −
