Before entering to this point , we must sure that our system have python.
So in command prompt I typed python –version, then I got python 3.8.5
Then we have to install mysql-connector module.
So in command prompt we type mysql-connector-python then enter, now the module will successfully install.

Now we will go to our environment, here I have used Atom IDE. Let’s see the following

Explanation :  Here first I imported mysql.connector module then there is a built in function named as connector() coming from mysql.connector module, taking three arguments like host, user, and password value. host=’localhost’ ; this localhost is the MySQL server name, default user name is root and password value what ever you have given that password value you specify. When connector() is invoking by mysql.connector then it is returning a variable(let mydb here) and that variable represents establishment of connection or connectivity.
