What is Python?

Python is a powerful multi paradigm computer programmin

optimized for programmer productivity, code readability, anquality.

Portable

Python compiles and runs on every major platform currently in use.

Python can be used on 21 different operating systems and environments.



Powerful

Python's toolset places it between traditional scripting languages (Tcl, Scheme and Pe

development languages ( C ,C++ and Java)



Mixable

Java Code to print “Hello World” :

class Hello {

public static void main (String[] args)

{ System.out.println (“Hello, world.”);

}

Python code to print “H

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

Offering a complete set of widgets, GTK+ is suitable for projects ranging from sm

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, m

most convenient and compatible toolkit to program with.



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 W

With pyjs you can write your JavaScript-powered web applications entirel

wxPython is a GUI toolkit for the Python programming language. It allows Python

programmers to create programs with a robust, highly functional graphical user

interface, simply and easily

Numeric and Scientific Programming

>>>a[4,:4:]

array([[44,45]

[54,55]])

Scipy Stack Includes modules for linear algebra, optimization, integration,

special functions, signal and image processing, statistics, genetic

algorithms

Numerical Python adds a fast, compact, multid

facility to Python. creating and manipulating n

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.



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

erformance, easy-to-use data structures and data

Python programming language.

Numeric and scientific programming

SymPy :SymPy is a Python library for symbolic mathematics. It is written entirely in

python and doesn’t need any external liberary.



Rapid Prototyping

Python is an ideal choice for prototyping because:

It is Dynamically typed language: Python doesn't require you to

declare the data type of a variable. This lets you write a function that isgeneric enough to handle any kind of data.

Python has Rich Set of Data-Structures: Built-in support for lists,dictionaries, sets, etc. reduces the time involved in hunting for a library

that provides you those basic data-structures.

Python is Expressive and Succinct: The algorithms that operate on thedata-structures are intuitive and simple to use. The final code is morereadable than a pseudo code.



Component Integration

It spans multiple platforms, middleware products, andapplication 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.



Getting Started With Python

Print “helloworld”

Print (“hello world”)

If else structure

a = 10

b = 20

If a>b:

print(“a is greater”)

else:print(“b is greater”)

for loop

for x in ran

print(x
