Mysql Database Config in Python

To establish a connection between the MySQL Client database and Python programming language. we need to install the "mysql-connector-python" module.

First, we need to install "pip" if haven't installed it already.

Here's how we can configure the Mysql database in Python using "mysql-connector-python" library:

Example:

pip install mysql-connector-python

Then, we can use it to establish a connection to your MySQL database and perform operations.

Here's a example of how we can configure and use MySQL in Python:

Import library and Database Connection Parameters:

Import `mysql.connector` library and create a configuration object with keys such as user, password, host, and database.

Example:

# import mysql.connector library
import mysql.connector

# Configuration parameters
# Such as: username, password, host url, database name
config = {
    'user': 'your_username',
    'password': 'your_password',
    'host': 'localhost',  # or your host address
    'database': 'your_database_name',
    'raise_on_warnings': True  # optional, for warnings to raise exceptions
}

Establish connection with connect() method and error handling:

Try to Establish a connection with the MySQL database by passing the configuration object to the `connect()` method.

Catch the error if it arises while connecting with the database in `except` statement.

Example:

try:
    # Establish a connection to the database
    connection = mysql.connector.connect(**config)

    if connection.is_connected():
        db_info = connection.get_server_info()
        print("Connected to MySQL Server version ", db_info)
        cursor = connection.cursor()


except mysql.connector.Error as error:
    print("Error occurred while connecting to MySQL:", error)

Close Connection:

Don't forget to close the connection once done using the "close()" method.

Example:

finally:
    if 'connection' in locals() and connection.is_connected():
        cursor.close()
        connection.close()
        print("MySQL connection is closed")

Code Snippet for Established MySQL Database Connection:

Example:

import mysql.connector

# Configuration parameters
config = {
    'user': 'your_username',
    'password': 'your_password',
    'host': 'localhost',  # or your host address
    'database': 'your_database_name',
    'raise_on_warnings': True  # optional, for warnings to raise exceptions
}

try:
    # Establish a connection to the database
    connection = mysql.connector.connect(**config)

    if connection.is_connected():
        db_info = connection.get_server_info()
        print("Connected to MySQL Server version ", db_info)
        cursor = connection.cursor()


except mysql.connector.Error as error:
    print("Error occurred while connecting to MySQL:", error)

finally:
    if 'connection' in locals() and connection.is_connected():
        cursor.close()
        connection.close()
        print("MySQL connection is closed")

Note:

Replace 'your_username', 'your_password', 'localhost', and 'your_database_name' with your actual MySQL credentials and database information.
Remember to handle exceptions and close the connection properly to avoid potential resource leaks.
