Define a class RING in Python with following specifications
Instance Attributes
- RingID # Numeric value with a default value 101
- Radius # Numeric value with a default value 10
- Area # Numeric value
Methods:
- AreaCal() # Method to calculate Area as
# 3.14*Radius*Radius
- NewRing() # Method to allow user to enter values of
# RingID and Radius. It should also
# Call AreaCal Method
- ViewRing() # Method to display all the Attributes 4Solution
class RING: # OR class RING( ): OR class RING(Object):
def __init__(self):
self.RingID=101
self.Radius=10
self.Area=0
def AreaCal(self):
self.Area=3.14*self.Radius*self.Radius
def NewRing(self):
self.RingID=input('Enter RingID')
self.Radius=input('Enter radius')
self.AreaCal() # OR AreaCal(self)
def ViewRing(self):
print self.RingID
print self.Radius
print self.Area
