This document provides an overview of the Python programming language. It discusses why Python was created, its key features like being an interpreted, dynamically typed language with indentation that counts. It also lists Python's core keywords and datatypes like numbers, strings, lists, dictionaries, tuples, files and other types. Finally, it outlines some of Python's basic operators like arithmetic, relational, bitwise, assignment and logical operators.
![Python's Core Datatypes
Object type Example
1234, 4, 999L , 3+ 4j , ..
Numbers
" Hello" , 'There' , ''' :) '''
Strings
[1 , [2 , "Three"], 4]
Lists
{"Food" : 1 , :"Tastes" : "Good":}
Dictionaries
(1 , "Is" , 'one' )
Tuples
myfile = open ("door", 'r' )
Files
Sets , Types, None , Booleans
Other types](https://image.slidesharecdn.com/from0tominesweeper-inpyside-120530050127-phpapp01/85/From-0-to-mine-sweeper-in-pyside-5-320.jpg)

- 1. Python.__init__(Qt) Dinesh
- 2. Why ANOTHER Language? ● Whats there in a language? - a few keywords and a little bit of grammar ● Then why NOT C/C++ ? - developing in Python is way faster!- lot less hassle ?- you wouldn't want to use a canon to kill a mosquito ;) ● Even then, why Python!? - Easy , Extensible, Everywhere!
- 3. So what IS Python? ● Interpreted Language :) (no more autotools, awk , cmake , qmake madness!) - But its an INTERPRETED Language!! :S ● Dynamically typed language. (no more int, char, float, etc.. ?!) ● Its Mixable. (You dont really have to build a class to print hello world) ● Indentation (and HENCE, the Beauty of your code!) Counts! ● Try using " help() " whenever needed...
- 4. Python's keywords and del from not while as elif global or with assert else if pass yield break except import print class exec in raise continue finally is return def for lambda try

- 6. Operators Unary + - ~ ** * / % + - Arithmetic , Boolean , Relational and Bitwise operators are all left to right associated >> << On the other hand, the assignment operator is & right associated ^ 9/3*3=9 | < <= == >= > != <> is not and *when confused, simply use parenthesis :) or
- 7. Hello Qt from PySide.QtGui import * import sys #Create a new application for me to work on myApplication = QApplication ( sys.argv ) #A new push button with a Label! hello = QPushButton ( " Hi There " ) #Show the button!! hello.show() #run my application myApplicatioin.exec_()
