What is pickle

Pickle is a Python module used for serializing and deserializing Python object structures, also known as marshalling or flattening. The main purpose of Pickle is to convert a Python object into a byte stream, which can then be saved to a file or transmitted over a network. When needed, this byte stream can be converted back into the original Python object. This is particularly useful for saving program state, sharing data between systems, or persisting data between program executions.

Here is an example of how to use Pickle in Python:

import pickle # Example data data = {'name': 'Alice', 'age': 30, 'city': 'New York'} # Serializing the data with open('data.pkl', 'wb') as file: pickle.dump(data, file) # Deserializing the data with open('data.pkl', 'rb') as file: loaded_data = pickle.load(file) print(loaded_data)
