How to use Python's pickle module

The video tutorial introduces Python's pickle module, which is used for serializing and deserializing objects. It explains how pickle can convert Python objects into a byte stream for storage or transfer and then reconstruct them. The tutorial demonstrates creating and pickling objects, highlighting that most Python objects can be pickled. It also warns about the security risks of using pickle, as it can execute malicious code if not handled carefully. The video suggests using JSON for safer data serialization when full object serialization is not required.
