Python module knowledge 4: serialization of Json/pickle and jsonpickle Serialization and deserialization Serialization: converts the basic data type of Python to a string. Deserialization: converts a string to the basic data type of Python. Two modules used for serialization in Python: Json is used for conversion between [String] and [python basic data type]

Serialized json, pickle, and jsonpickle in python What is Json: JSON (JavaScript Object Notation) is a lightweight data exchange format. Easy for reading and writing, and easy for machine parsing and generation. Json uses a completely language-independent text format, but it

In Python, serialization can be interpreted as converting the encoded format of an object in Python to a string in JSON (pickle) format, which can be interpreted as converting a string in JSON (pickle) format into an encoded format for an object in PythonTo give a simple example, we write the Python program in the Vmva
