Introduction to Python ProgrammingIntroduction Open source general-purpose. Multiplatform programming

language Object Oriented, Procedural, Functional Easy to interface with C/ObjC/Java/Fortran Easy to interface with C++ (via SWIG) Great interactive environment Python 'philosophy' emphasis readability, clarity and simplicity The Interactive Interpreter it is very easy to learn and understand. It is extensible, you can easily plug new modules in your Python

installation and extend its functionality

Introduction to Python ProgrammingGet Started with Python program#one.pyx = 34y = 'Hello' y = y + 'World'print(x)print(y)

Open new window and type in the program save as one.py and then run module.Output:34HelloWorld

# kbinput.pyname = input('What is your name:')

print('It is good to meet you mr ', name)www.collaborationtech.co.in

Introduction to Python Programming# Data Format exampleage = 25name = 'Swaroop'print('{0} is {1} years old'.format(name, age))print('Why is {0} playing with that python?'.format(name))data=1/6print('{0:.3}'.format(data) ) # decimal (.) precision of 3 for float# fill with underscores (_) with the text centered (^) to 11 widthprint('{0:_^11}'.format('hello') )print( '{name} wrote {book}'.format(name='Swaroop', book='A Byte of Python') )

Introduction to Python Programming# Using If and elif Statement - compute.pya = input('enter value a:')b = input('enter value b:')x= int(a)y=int(b)ch = input('enter your option(1.add 2.subtract):')choice= int(ch)if choice == 1: print('sum of ' + a + 'and ' + b +'=', x+ y )elif choice == 2: print ( ' subtraction of '+ a + ' and ' + b + 'is ' , x- y )else: print('Invalid Option:')

Introduction to Python Programming# Using for Statement

print('Using for loop Statement')for x in range(20):

print('Still in the loop: ', x)print('Outside of the for loop')

# for with range for x in range(3,20): print('Still in the loop: ‘, x) print ('Outside of the loop')

val=input('enter the value for x')x=int(val)for i in range(x):if(i%2==0): continue print(‘value:’,i) print('done')
