    While working with Python we need to work with databases, they may be of different types like MySQL, SQLite, NoSQL, etc. In this article, we will be
    looking forward to how to connect MySQL databases using MySQL Connector/Python.
    MySQL Connector module of Python is used to connect MySQL databases with the Python programs, it does that using the Python Database API Specification v2.0 (PEP 249). It uses the Python standard library and has no dependencies.
     

    Connecting to the Database

    In the following example we will be connecting to MySQL database using connect()
    Example:
     

    Python3

    import mysql.connector

    conn = mysql.connector.connect(user = 'username',

                                   host = 'localhost',

                                  database = 'database_name')

    print(conn)

    conn.close()

    Output:
     

    Also for the same, we can use
    connection.MySQLConnection() class instead of connect():
    Example:
     

    Python3

    from mysql.connector import connection

    conn = connection.MySQLConnection(user = 'username',

                                  host = 'localhost',

                                  database = 'database_name')

    print(conn)

    conn.close()

    Output:
     

    Another way is to pass the dictionary in the connect() function using ‘**’ operator:
    Example:
     

    Python3

    from mysql.connector import connection

    dict =

      'user': 'root',

      'host': 'localhost',

      'database': 'College'

    conn = connection.MySQLConnection(**dict)

    print(conn)

    conn.close()

    Output:
     

    Abstract

    This manual describes how to install and configure MySQL Connector/Python, a self-contained Python driver for communicating with MySQL servers, and how to use it to develop database applications.

    MySQL Connector/Python 8.0 is highly recommended for use with MySQL Server 8.0, 5.7, and 5.6. Please upgrade to MySQL Connector/Python 8.0.

    For notes detailing the changes in each release of Connector/Python, see
    MySQL Connector/Python Release Notes.

    For legal information, see the Legal Notices.

    For help with using MySQL, please visit the MySQL Forums, where you can discuss your issues with other MySQL users.

    What is MySQL Connector used for?

    MySQL Connectors provide connectivity to the MySQL server for client programs. APIs provide low-level access to MySQL resources using either the classic MySQL protocol or X Protocol.

    Is MySQL Connector necessary?

    This is necessary because each make of database server has its own specific protocol for transporting requests to, and results from, the server to application programs. Don’t worry about matching connector and server versions unless your server is really ancient (v4 or earlier).

    Do I need connector Python for MySQL?

    Python needs a MySQL driver to access the MySQL database. In this tutorial we will use the driver “MySQL Connector”. We recommend that you use PIP to install “MySQL Connector”. PIP is most likely already installed in your Python environment.

    How do I run MySQL Connector?

    Installation: To install Python-mysql-connector module, one must have Python and PIP, preinstalled on their system. To check if your system already contains Python, go through the following instructions: Open the Command line(search for cmd in the Run dialog( + R).
