python-mysqlHow can I use Python to retrieve data from MySQL?
You can use Python to retrieve data from MySQL by using the Python MySQL connector library. This library provides an interface for connecting to a MySQL database server and executing SQL statements.
Example code
import mysql.connector
# Connect to the database
mydb = mysql.connector.connect(
host="localhost",
user="user",
passwd="passwd",
database="mydatabase"
)
mycursor = mydb.cursor()
# Execute a query
mycursor.execute("SELECT * FROM customers")
# Fetch all the results
myresult = mycursor.fetchall()
# Print the results
for x in myresult:
print(x)
Output example
(1, 'John', 'Lowstreet 4')
(2, 'Peter', 'Lowstreet 5')
(3, 'Amy', 'Lowstreet 6')
The code consists of the following parts:
- Importing the MySQL Connector library -
import mysql.connector
- Connecting to the database -
mydb = mysql.connector.connect(host="localhost", user="user", passwd="passwd", database="mydatabase")
- Creating a cursor object -
mycursor = mydb.cursor()
- Executing a query -
mycursor.execute("SELECT * FROM customers")
- Fetching the results -
myresult = mycursor.fetchall()
- Printing the results -
for x in myresult: print(x)
