Program (Code):

class Book:
   title="" # to store the title
   author="" # to store the author name
   price=0.0 # to store the price
   def __init__(self,title,author,price): # constructor to initialise the above variables
       self.title=title
       self.author=author
       self.price=price
def main(): # main method
   obj=Book("Java","Sangam",5.0) # object creation
   print obj.title
   print obj.author
   print obj.price

if __name__ == "__main__":
   main()

Program (Screenshot):

1 class Book: title-"" # to store the title author.' " # to store the author name price-0.0 # to store the price def-init-(self, title,author,price): # constructor to initialise the above variables 4 self.title-title self.author-author self.price-price 6 9 def main(): # main method 10 obj Book("Java", "Sangam",5.0) print obj.titl print obj.author print obj.price # object creation 12 13 15 if name 16 main" main()

Output:

C:WINDOWS system321cmd.exe C:NUser Sunny Desktop>python Book.py Java Sangam Users Sunny Desktop>

2.

Program (Code):

def main(): # main function
   while 1: # infinte while loop
       num=raw_input("enter a number to get its square:") # scanning input in string format
       if num.isdigit(): # isdigit() returns true if string contains only digits
           num=int(num) # converting input in string formta to integer
           print num*num # computing square of the number
           break
if __name__ == "__main__":
   main()

Program (Screenshot)

def main(): # main function while 1: # infinte while loop num-raw-input("enter a number to get its square :") # scanning input in string format If num. įsdigit(): # 1sdigit() returns true if string contains only digits 4 num-int(num) # converting input in string formta to integer print num num #|computing square of the number break 6 7 8 if name"main 9 main()

Output:

C:WINDOWS system321cmd.exe C:NUser Sunny Desktop>python test.py enter a number to get its square mc enter a number to get its square:bc enter a number to get its square :6ma enter a number to get its square :6 6 Users Sunny Desktop>
