It’s important to note that a shelve file is not a database, and it does not provide any advanced features such as transactions, indexes, or query capabilities.
The data stored in a shelve file can be accessed just like a dictionary, using the key to retrieve the associated data. This makes the data stored in a shelve file easy to access and persistent between multiple sessions. The module uses a key-value pairing system, similar to a dictionary, where the key is used to access the stored data.Ī shelve file is a binary file that stores the data in a serialized format using the pickle module.
It provides a simple and easy-to-use interface for storing and retrieving Python objects. The Shelve module is a part of the Python Standard Library and is included with all installations of Python.

By the end of this tutorial, you will have a solid understanding of how to use Python Shelve in your own projects. You will see how to create and open a shelve file, store and retrieve data, modify data, delete data, and close the shelve file. In this tutorial, you will learn how to use Python’s Shelve module to store and retrieve data in a convenient and efficient manner. The data is stored in a binary format, making it a good option for data that doesn’t need to be human-readable. This means that the data stored in a shelve file can be easily accessed between multiple sessions, and it will persist even after the Python process has ended. Shelve is a persistent storage system for Python objects, and it uses the pickle module to serialize and deserialize the data. The data stored in a shelve file can be anything from simple variables like strings and integers to more complex data structures like lists and dictionaries. This makes it a perfect choice for small to medium-sized projects where a full-fledged database management system like MySQL or PostgreSQL is overkill. Python’s Shelve module allows developers to store and retrieve Python objects easily and quickly, just like a database.
