Answer:
The pickle
module in Python is used for serializing and deserializing Python objects to a byte stream, allowing objects to be saved to disk and restored again. The pickle
module converts complex Python objects into a stream of bytes that can be easily stored to disk or transmitted over a network. The deserialization process converts the byte stream back into a Python object.
Here is an example of using the pickle
module to serialize and deserialize a Python object:
import pickle # Original Python object data = { "name": "John Doe", "age": 30, "email": "johndoe@example.com" } # Serializing the Python object to a byte stream with open("data.pickle", "wb") as f: pickle.dump(data, f) # Deserializing the byte stream back into a Python object with open("data.pickle", "rb") as f: data = pickle.load(f) print(data) # Output: {'name': 'John Doe', 'age': 30, 'email': 'johndoe@example.com'}
