pickle

1. Pickle is a command line tool in Python used for serializing and deserializing Python objects.
2. It allows you to convert a Python object into a byte stream representation, which can be stored in a file or transferred over a network.
3. The pickle module in Python provides the necessary functions for this serialization process.
4. By pickling an object, you can save its current state and retrieve it later when needed, even across different program executions.
5. Pickle supports a wide range of Python data types, including integers, floats, lists, dictionaries, and even custom classes and objects.
6. It can handle complex data structures, making it useful for applications like saving machine learning models or caching data.
7. The pickled data is stored in a binary format, so it is not human-readable.
8. You can pickle multiple objects into a single file, as long as you maintain the proper order when unpickling.
9. However, caution should be exercised when unpickling data from an untrusted source, as it may lead to code execution vulnerabilities.
10. Despite its flexibility, pickle is primarily recommended for use within a trusted environment and is not suitable for transferring data between different programming languages.
