Aim:
To demonstrate the Python
programs and Python
program connectivity with MYSQL
database.
Introduction
Python is an easy to learn, powerful programming language. It has efficient high-level data
structures and a simple but effective approach to object-oriented programming. Python’s elegant syntax
and dynamic typing, together with its interpreted nature, make it an ideal language for scripting and
rapid application development in many areas on most platforms.
Python is a high-level programming language.It is an easy to learn, powerful programming
language. It has efficient, high-level data structures and a simple yet effective approach to object
oriented programming.
Python’s elegant syntax and dynamic typing, together with it's interpreted nature, makes it an
ideal language for scripting and rapid application development in many areas and on most platforms.
The Creator of this Language is Guido van Rossum. He named this language after the BBC show
“Monty Python‘s Flying Circus”. But he doesn’t particularly like snakes that kill animals for food by
winding their long bodies around them and crushing them.
Python runs on Windows, Linux/Unix, Mac OS X, and has been ported to the Java and .NET
virtual machines.
Python is free to use, even for commercial products, because of its OSI-approved open source
license.
Steps to execute python programs:
1.
Open the vi editor and write the program
2.
Save the program with .py as extension
3.
Execute the program using python filename.py
Program : CREATE TABLE PROGRAM USING PYTHON
#!/usr/bin/python
import MySQLdb
# Open database connection
db = MySQLdb.connect("localhost","root","","student" )
# prepare a cursor object using cursor() method
cursor = db.cursor()
# Drop table if it already exist using execute() method.
cursor.execute("DROP TABLE IF EXISTS student ")
# Create table as per requirement
sql = """CREATE TABLE student ( FIRST_NAME CHAR(20) NOT NULL,LAST_NAME
CHAR(20), AGE INT, SEX CHAR(1),
cursor.execute(sql)
# disconnect from server
db.close()
Output:
Go to terminal:
[fosslab@fosslab ~]$ su Password: (admin123)
[root@fosslab ~]# mysql -u root
