Chapter 17 Conclusion
In this chapter, we've taken an in-depth look at how Python interacts with SQL databases using various libraries such as sqlite3, psycopg2, and mysql-connector-python. We started by discussing the sqlite3 module and how it can be used to connect to SQLite databases, execute SQL queries, and fetch results. We then explained how to use Python's DB-API 2.0 interface to interact with different types of databases.
We went over the basic CRUD (Create, Read, Update, Delete) operations and how they can be performed on a database using Python. Along the way, we also learned about the importance of handling transactions in Python, which can significantly impact the consistency and integrity of our database.
We then delved into error and exception handling, which is a crucial aspect of writing robust, error-free code. We looked at some of the common exceptions that can arise when working with SQL in Python and learned how to handle them.
