How to connect MYSQL Database in Python

Connecting to a MySQL database in Python is a straightforward process that allows you to access and manipulate the data stored in a MySQL database. In this article, we will go over the basics of how to connect to a MySQL database in Python.

First, we need to install a library called mysql-connector-python. This library allows us to connect to a MySQL database and execute SQL queries. You can install it by running the following command in your command prompt or terminal: pip install mysql-connector-python

Once the library is installed, we need to import it into our Python script. We can do this by using the import statement, like so: import mysql.connector

Next, we need to create a connection to the MySQL server. We do this by instantiating the mysql.connector.connect class and passing in the following parameters: host, user, password, and database. The host parameter is the IP address or hostname of the MySQL server. The user and password parameters are the username and password that you use to connect to the MySQL server. The database parameter is the name of the database that you want to connect to.

Once the connection is established, we can execute SQL queries on the MySQL server. We can do this by creating a cursor object, which will allow us to execute SQL queries. We do this by calling the cursor() method on our connection object.

We can then execute the SQL query on the MySQL server by calling the execute() method on our cursor object and passing in the SQL query as a parameter.

Lastly, we need to close the connection and cursor, This is important because it ensures that the connection to the MySQL server is closed and the resources are freed.
