What is Python?

• Python is a powerful multi paradigm computer
  programming language, optimized for programmer
  productivity, code readability, and software
  quality.

Python a Complete Language

• Python provides simplicity and
• ease of use of scripting
• Language , along with more
• advanced software-
• engineering tools typically
• found in compiled languages
• which makes Python useful for
• large-scale development
• projects.

Features of Python
Object oriented
Mixable
Free
Powerful
Easy to learn
Portable
Easy to use
6
Portable
Python compiles and runs on every major platform
currently in use. Python can be used on 21
different operating systems and environments.
7
Powerful
Python's toolset places it between traditional
scripting languages (Tcl, Scheme and Perl) and
systems development languages ( C ,C and Java)
8
Mixable

• Python programs can be easily glued to
  components written in other languages.

9
Ease of Syntax

• Java Code to print Hello World

• Python code to print Hello World

• class Hello
• public static void main (String args)
• System.out.println (Hello, world.)

• print Hello, World

Major uses of Python
Scientific and numeric programming
15
GUIs

Camelot provides components for building
applications on top of Python, SQLAlchemy and Qt.
inspired by the Django admin interface
GTK, or the GIMP Toolkit, is a multi-platform
toolkit for creating graphical user interfaces.
Offering a complete set of widgets, GTK is
suitable for projects ranging from small one-off
toolsto complete application suites.
Kivy is a Python library for development of
multi-touch enabled media rich applications. The
aim is to allow for quick and easy interaction
design and rapid prototyping, while making your
code reusable and deployable.
Tkinter has the advantage of being included with
the Python standard library, making it the most
convenient and compatible toolkit to program with.
16

PyQt is a set of Python v2 and v3 bindings
for Digia's Qt application framework and runs on
all platforms supported by Qt including Windows,
MacOS/X and Linux.
pyjs is a Rich Internet Application (RIA)
Development Platform for both Web and Desktop.
With pyjs you can write your JavaScript-powered
web applications entirely in Python.
wxPython is a GUI toolkit for the Python programm
ing language. It allows Python programmers to
create programs with a robust, highly functional
graphical user interface, simply and easily
17
Numeric and Scientific Programming

•  

Scipy Stack Includes modules for linear algebra,
optimization, integration, special functions,
signal and image processing, statistics, genetic
algorithms
Numerical Python adds a fast, compact,
multidimensional array facility to Python.
creating and manipulating numerical data
gtgtgta4,4 array(44,45 54,55)
IPython is a command shell  for interactive
computing developed for the Python programming
language that offers enhanced  introspection
,rich media, additional shell syntax, tab
completion and rich history.
18
Numeric and scientific programming
Matplotlib Matplotlib is a python 2D plotting
library which produces publication quality
figures in a variety of hardcopy formats and
interactive environments across platforms.Like
Pie charts,simple plots,Histograms etc.

Pandas pandas is an open source, BSD-licensed
library providing high-erformance, easy-to-use
data structures and data analysis tools for the
Python programming language.
SymPy SymPy is a Python library for symbolic
mathematics. It is written entirely in python
and doesnt need any external liberary.

• Rapid Prototyping

Python is an ideal choice for prototyping because
20
Component Integration
It spans multiple platforms, middleware products,
and application domains. Python can fulfill an
important integration role in the design of large
applications with a long life expectancy. It
allows a fast response to changes in user
requirements that require adapting the
higher-level application logic without changing
the fundamental underlying components. It also
allows quick adaptation of the application to
changes in the underlying components.
