Python pickle Module
Example
Serialize a Python object to bytes and back:
import pickle
data = {"name": "Emil", "age": 30}
b = pickle.dumps(data, protocol=pickle.HIGHEST_PROTOCOL)
print(pickle.loads(b)["name"])

Definition and Usage
The pickle module converts Python objects to a byte stream and restores them later.
Use it to save in-memory data for later use or transfer, but never unpickle data you don’t trust.
