python-mysqlHow do Python and MySQL compare to MariaDB?

Python and MySQL can be used together to create powerful applications that can store and retrieve data from a MySQL database. However, MariaDB is a newer, more advanced open source database that provides a more robust feature set than MySQL.

MariaDB supports improved performance, scalability, and security compared to MySQL. For example, MariaDB supports advanced features such as row-level locking, which allows multiple transactions to be processed simultaneously.

MariaDB also supports a wide range of storage engines, such as XtraDB, which provides improved performance and scalability compared to MySQL’s MyISAM engine.

Python can be used to connect to MariaDB using a variety of database drivers, such as PyMySQL, which provides an interface compatible with MySQL.

Example code

import pymysql

# Connect to the database
conn = pymysql.connect(host="localhost", user="root", password="password", db="testdb")

# Execute a query
cur = conn.cursor()
cur.execute("SELECT * FROM users")

# Print the results
for row in cur:
    print(row)

# Close the connection
conn.close()

Output example

('John', 'Smith', '[email protected]')
('Jane', 'Doe', '[email protected]')

• import pymysql: imports the PyMySQL library, which provides an interface compatible with MySQL.
• conn = pymysql.connect(host="localhost", user="root", password="password", db="testdb"): creates a connection to the MariaDB database.
• cur = conn.cursor(): creates a cursor object, which is used to execute queries.
• cur.execute("SELECT * FROM users"): executes a query to select all records from the users table.
• for row in cur:: iterates over the results of the query and prints them.
• conn.close(): closes the connection to the database.
