MySQL Connector/Python enables Python programs to access MySQL databases, using an API that is compliant with the Python Database API Specification v2.0 (PEP 249). It also contains an implementation of the X DevAPI, an Application Programming Interface for working with the MySQL Document Store.

Below example shows the example to use the class defined in ckmysql.py
test.py
from ckmysql import ckmysql
db = ckmysql() # if you want to use the default settings defined in the class
r = db.query("select * from test limit 5")
print(r)
Above case is based in using the default database connection information and below is based in the connection environment like user_id, password, server and database.
from ckmysql import ckmysql
db = ckmysql( 'my_id', 'my_password', '127.0.0.1', 'my_db')
r = db.query("select * from test limit 5")
print(r)
