Question

What module do you import if you want to pickle objects?

Short answer

Answer: Pickling in Python is the process of converting objects into a byte stream that can be stored or transmitted and later reconstructed back into the original object. The module used for pickling objects in Python is called 'pickle'. To import this module, you can use `import pickle`.

Step-by-step solution

Introducing Pickling

Pickling is the process in Python where objects, such as dictionaries, lists, or custom objects, are converted into a byte stream. This byte stream can be stored or transmitted and later reconstructed into the original object. This is useful, for example, in cases where one wants to save the program's state and retrieve it later. To perform pickling in Python, we need to use a specific module.

Pickle Module

The module used for pickling objects in Python is called 'pickle'. To import this module, you need to type: ```python import pickle ``` Once the module is imported, you can use its methods, like `pickle.dumps(obj)` for pickling an object and `pickle.loads(byte_stream)` for reconstructing the original object from the byte stream.
