Have you ever needed to store a complex data structure in Python, or transmit it over a network, but struggled to find a simple solution? Pickling and unpickling in Python might be the answer to your problem. Pickling in Python refers to the process of converting a Python object into a binary representation, which can then be stored in a file or transmitted over a network. Unpickling is the reverse process of converting the binary data back into a Python object. This process is useful for applications that need to store or transmit data between different machines or across different sessions of the same program. The pickle module in Python provides a simple and efficient way to perform pickling and unpickling operations.
