python-mysqlHow do I format a MySQL query in Python?

The Python Database API Specification v2.0 provides a common interface for various database systems. To access MySQL databases from Python, you need to install the MySQL Connector/Python package.

To format a MySQL query in Python, you need to use the following syntax:

import mysql.connector

mydb = mysql.connector.connect(
  host="localhost",
  user="yourusername",
  passwd="yourpassword"
)

mycursor = mydb.cursor()

sql = "SELECT * FROM customers WHERE address = %s"
adr = ("Yellow Garden 2", )

mycursor.execute(sql, adr)

myresult = mycursor.fetchall()

for x in myresult:
  print(x)

The output of the above code will be:

('John', 'Highway 21', 'Yellow Garden 2')

The code consists of the following parts:

1. import mysql.connector: imports the MySQL Connector/Python package.
2. mydb = mysql.connector.connect(): creates a connection to the MySQL database.
3. mycursor = mydb.cursor(): creates a cursor to execute the query.
4. sql = "SELECT * FROM customers WHERE address = %s": defines the SQL query.
5. adr = ("Yellow Garden 2", ): defines the parameters for the query.
6. mycursor.execute(sql, adr): executes the query with the parameters.
7. myresult = mycursor.fetchall(): fetches the results of the query.
8. for x in myresult:: loops through the results.
9. print(x): prints each result.

For more information, please refer to the MySQL Connector/Python documentation.
