Introduction to Python

 

Python is an object oriented, procedural, and high level language. It was developed by Guido Von Rossum in 1990. In Python there are classes, exceptiona, modules and data types. It is derived from the other languages C, C++, Unix cell and many others. Python is a conveniently transported, widen, large standard library.

Version of Python

The following are the versions of the Python language:
Python 1.0- January, 1994
Python 2.0- October 16, 2000
Python 3.0- December 3, 2008
The latest version of the Python language was launched May 15, 2013. The new features in this version is syntax and a library module.

Basic Python Language Element

In the Python language the data types are string, float and integer. An integer is like a= 5*4 and float like d= 6.335. For introducing the string we use double quotes ( " " ) or single quotes ( ' ' ). It is also possible to use triple quotes ( """ """" ). In this language use # for comments, like " # This is my Article.. ".
The basic operators are as in other programming languages that use addition, subtraction and multiplication. Python supports strings using the addition operator. It will support a single line statement. The example of a one-line if clause is:

 

The output is:

 

Using a For loop in the Python language means executing the statement many times. It is slightly different here, the user introduces their own iterables by creating objects. An example of a For loop from 1 to 3, running 3 times is as in the following:

 

The output is:

Features

In the Python language there are also the loop statement like a for loop, nested loop and using break and continue loop control statements. The Python language also supports a database API, database server like MySQL, Oracle. There is also support for multithreading, networking. The Python language uses some library like "smtplib", that is used to send mail.

Python is a dynamically typed, strong language, It supports the internet communication engine ICE. It runs everywhere, in platforms like Windows, Mac, Linux, Unix and many other operating systems.

Summary

This article was a small introduction to the Python language, which is easy to learn and easy to understand. Python is an interactive, interpreted, and object oriented language.
