Python - Programming Language
Python is a powerful high-level, object-oriented programming
language created by Guido van Rossum.
It has simple easy-to-use syntax, making it the perfect language for
someone trying to learn computer programming for the first time.
Python is easy to learn yet powerful and versatile scripting language
which makes it attractive for Application Development.
Python's syntax and dynamic typing with its interpreted nature,
make it an ideal language for scripting and rapid application
development in many areas.
Python supports multiple programming pattern, including object
oriented programming, imperative and functional programming or
procedural styles.
Python is not intended to work on special area such as web
programming. That is why it is known as multipurpose because it
can be used with web, enterprise, 3D CAD etc.

History of PHP Programming Language
We don't need to use data types to declare variable because it
is dynamically typed so we can write a=10 to declare an integer
value in a variable.
Python makes the development and debugging fast because there
is no compilation step included in python development and edit-
test-debug cycle is very fast.
Python is a fairly old language created by Guido Van Rossum. The
design began in the late 1980s and was first released in February
1991.

Why the name Python?
No. It wasn't named after a dangerous snake. Rossum was
fan of a comedy series from late seventies. The name
"Python" was adopted from the same series "Monty
Python's Flying Circus".

Python Features
There are a lot of features provided by python programming
language
1) Easy to Use:
Python is easy to very easy to use and high level language. Thus it is
programmer-friendly language.
2) Expressive Language:
Python language is more expressive. The sense of expressive is the
code is easily understandable.
3) Interpreted Language:
Python is an interpreted language i.e. interpreter executes the code
line by line at a time. This makes debugging easy and thus suitable
for beginners.
4) Cross-platform language:
Python can run equally on different platforms such as Windows,
Linux, Unix , Macintosh etc. Thus, Python is a portable language.

Python Features
5) Free and Open Source:
Python language is freely available(www.python.org).The source-
code is also available. Therefore it is open source.
6) Object-Oriented language:
Python supports object oriented language. Concept of classes and
objects comes into existence.
7) Extensible:
It implies that other languages such as C/C++ can be used to
compile the code and thus it can be used further in your python
code.
8) Large Standard Library:
Python has a large and broad library.
9) GUI Programming:
Graphical user interfaces can be developed using Python.
10) Integrated:
It can be easily integrated with languages like C, C++, JAVA etc.

Python programming language is being updated regularly with new
features and support. There are a lot of updation in python

Applications of Python
Python as a whole can be used in any sphere of development.
Let us see what are the major regions where Python proves to be
handy.
1) Console Based Application
Python can be used to develop console based applications. For
example: IPython.
2) Audio or Video based Applications
Python proves handy in multimedia section. Some of real
applications are: TimPlayer, cplay etc.
3) 3D CAD Applications
Fandango is a real application which provides full features of CAD.
4) Web Applications
Python can also be used to develop web based application. Some
important developments are: PythonWikiEngines, Pocoo,
PythonBlogSoftware etc.

Applications of Python
5) Enterprise Applications
Python can be used to create applications which can be used within
an Enterprise or an Organization. Some real time applications are:
OpenErp, Tryton, Picalo etc.
6) Applications for Images
Using Python several application can be developed for image.
Applications developed are: VPython, Gogh, imgSeek etc.
There are several such applications which can be developed using
Python
