Python is a simple yet powerful programming language that can be used for a wide range of applications. It has an easy to read syntax and is free and open source. Python code is interpreted at runtime and variable types are automatically determined. Python supports object oriented programming concepts like classes, inheritance and modules. It can be used for tasks like text processing, web development, scientific computing, and more. Guido van Rossum created Python in 1991, building upon languages like Perl and Java.

etc.,

23. Examples!

25. print “Hello World”

26. No Semicolons !

27. Variables
colored_index_cards

28. No Need to Declare Variable Types !
Python Knows Everything !

29. value = 10
print value
value = 100.50
print value
value = “This is String”
print value * 3

30. Input

31. name = raw_input(“What is Your name?”)
print "Hello" , name , "Welcome"

32. Indentation

33. You have to follow the
Indentation
Correctly.
Otherwise,
Python will beat you !

35. Discipline
Makes
Good

36. Flow

37. score = input("Enter the value
of the score- ")
if score >=5000 :
print "you win"
elif score <=0:
print "you lose"
else:
print "Current score:",score
print "donen"

38. Loop

39. for i in range(1, 5):
print i
print 'The for loop is over'
