Python MySQL
Python MySQL:
To connect Python with a MySQL database, you can use the MySQL Connector/Python module, which provides an interface for working with MySQL databases using Python.
Here’s an example of how to connect to a MySQL database, execute queries, and fetch results:
First, you need to install the MySQL Connector/Python module if you haven’t already. You can install it using pip:
pip install mysql-connector-python
Once the module is installed, you can use the following code to connect to a MySQL database:
import mysql.connector
# Establish a connection to the MySQL database
cnx = mysql.connector.connect(
host='localhost', # Replace with the database host
user='username', # Replace with your MySQL username
password='password', # Replace with your MySQL password
database='database_name' # Replace with the name of your database
)
# Create a cursor object to execute queries
cursor = cnx.cursor()
# Execute a query
query = "SELECT * FROM table_name"
cursor.execute(query)
# Fetch the results
results = cursor.fetchall()
# Iterate over the results
for row in results:
print(row)
# Close the cursor and the connection
cursor.close()
cnx.close()
Make sure to replace the placeholders (host, user, password, database_name, table_name) with the appropriate values for your MySQL setup. This example assumes you have a table named table_name in your database.
You can modify the query to perform insertions, updates, or any other SQL operations based on your requirements.
Remember to close the cursor and the connection once you’re done with the database operations to release resources properly.
