Pickle

In programming, Pickle is a tool used to save complex data structures—such as lists, dictionaries, or custom objects—by converting them into a format that can be stored to a file or transmitted over a network. Later, this data can be restored to its original form. Think of it like packaging a detailed document so it can be stored or sent, then unwrapped back into the original document later. Pickle is mainly used in Python to make it easy to save and load data without manually converting each component.
