Python Programming For Beginners part 4

Task 1: Write a program using object oriented method to print "Hello I am a constructor on the screen". 

# Task No : 1
print("        -----Hello word-----")
class hello():
    def dsp(self):
        print("Hello I am a constructor on the screen")
if __name__=="__main__":
    hp=hello()

    hp.dsp()

Task 2: Write a program using object oriented method to calculate the area. It should require two attributes width W and Height H. 

# Task No : 2
class Area:
    pass 
R=Area()
R.width = 5
R.height = 7
print("Hieght is : ",R.width)
print(" Width is : ",R.height)

print("Total Area Is :",R.width*R.height)

Task 3: Write a program using OOP method to calculate the area. It should require two values of attributes W and H (the user will enter the values of w and h in run time). 

# Task No : 3
class Area:
    def __init__(self):
        self.w = float(input("Enter the value of w :"))
        self.h = float(input("Enter the value of h :"))
        print("Total Area Is",self.w*self.h)

R=Area()
