2. Start a Python 3 interactive session and import the "mysql.connector" module.

fyicenter> python3 
Python 3.8.0 (v3.8.0:fa919fdf25) 

>>> import mysql.connector

3. Call the connect() method to establish a connection to a MySQL server with given accessing information. It returns a MySQLConnection object representing the established connection.

>>> con = mysql.connector.connect(host="", port=3306,
...     user="guest", password="retneciyf")

>>> print(con)
<mysql.connector.connection.MySQLConnection object at 0x10701b640>

4. Use MySQLConnection methods and properties to see the MySQL environment.

>>> con.get_server_info()

>>> con.cmd_statistics()
{'Uptime': 1726469, 'Threads': 4, 'Questions': 64496, 'Slow queries': 0,

>>> con.user

>>> con.charset

5. Call cmd_init_db() method to set the default database to a database instance that your user name is allowed to use.

>>> con.cmd_init_db("test")
{'field_count': 0, 'affected_rows': 0, 'insert_id': 0, ...

>>> con.database

6. Run SQL statements on the connection as shown in next tutorials.

7. Close the connection at the end.
