Python 3.7.3 : Use python with MySQL and MariaDB.

If you want to use MariaDB databases with python then you need to install the MySQL.
Use the pip tool to install the mysql-connector-python python module:

C:\Python373\Scripts>pip install mysql-connector-python
Collecting mysql-connector-python
...
Installing collected packages: mysql-connector-python
Successfully installed mysql-connector-python-8.0.16

The information about python module named mysql-connector-python version 8.0.16 can be found at this web page.
For the test, I install MariaDB from the official website with user root and my password.
Let's test the python module for MariaDB:

C:\Python373>python.exe
Python 3.7.3 (v3.7.3:ef4ec6ed12, Mar 25 2019, 21:26:53) [MSC v.1916 32 bit (Inte
l)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import mysql
>>> import mysql.connector as mariadb

After install, start the command prompt of MariaDB and test it:

C:\Windows\System32>mysql -u root -p
Enter password: ****
