To make the process smooth and straightforward, I've decided to use the application. You don't have to do so, as you can do everything straight from the Python or even from the Terminal. We'll start with the insertions, as that makes the most sense for an empty database Using Python, you can connect and run queries against a MySQL database on your server. In this example, we've created a test script named test_db.py and placed it in our cgi-bin folder. We also updated the file's permissions to 755. We also used the following settings within the code: database name: inmoti6_pytest; database user: inmoti6_pytes Accessing MySQL from a Python application requires a database driver (also called a connector). While it is possible to write a driver as part of your application, in practice most developers use an existing open source driver. There was a major issue with MySQL drivers since the introduction of Python 3

Python Database API is a set of standards recommended by a Special Interest Group for database module standardization. Python modules that provide database interfacing functionality with all major database products are required to adhere to this standard. DB-API standards were further modified to DB-API 2.0 by another Python Enhancement. As a language for creating database clients, Python is perfectly fine for most applications. Most database-heavy applications will spend a lot of time networking, so they won't benefit all that much by using a performance language like C++ over.
