How to use "pymysql" module from PyMySQL Package produced by pypi.org?

"pymysql" is a Python module in the PyMySQL package provided by pypi.org for MySQL database connection.

"pymysql" implements "PEP 249 -- Python Database API Specification v2.0" at https://www.python.org/dev/peps/pep-0249/. You can follow this tutorial to try it.

1. Install "PyMySQL" package that contains the "pymysql" module. Do not use the outdated "MySQLdb" package.

fyicenter> pip3 install pymysql

...
Successfully installed pymysql-1.0.2

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

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

>>> import pymysql

>>> pymysql.1.03
'1.0.2'

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

>>> con = pymysql.connect(host="127.0.0.1", port=3306,
...     user="guest", password="retneciyf")

>>> print(con)
<pymysql.connections.Connection object at 0x107108f40>

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

>>> con.get_server_info()
'8.0.17'

>>> con.user
b'guest'

>>> con.charset
'utf8mb4'

>>> con.encoding
'utf8'

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

>>> con.select_db("test")
>>> 

>>> con.db
b'test'

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

7. Close the connection at the end.

>>> con.close()
