Classes In Python

Question
CBSEENCO12011541
Wired Faculty App

Write two methods in Python using the concept of Function Overloading (Polymorphism) to perform the following operations:
(i) A function having one argument as side, to calculate Area of Square as side*side
(ii) A function having two arguments as Length and Breadth, to calculate Area of Rectangle as Length*Breadth.

Solution
def Area(side):
	print side*side
def Area(length,breadth):
	print length*breadth

If you run the code, the second Area(B, H) definition will overwrite/override the first one because python does not support function overloading “ as illustrated in the example shown above ”.

(ii) A function having two arguments as Length and Breadth, to calculate Area of Rectangle as Length*Breadth.

 

class Exam:
	Regno=1
	Marks=75
	def __init__(self,r,m): #function 1
		self.Regno=r
		self.Marks=m
	def Assign(self,r,m): #function 2
		Regno = r
		Marks = m
	def Check(self): #function 3
		print self.Regno, self.Marks
		print Regno, Marks

(i) In the above class definition, both the functions - function 1 as well as function 2 have similar definition. How are they different in execution?

(ii) Write statements to execute function 1 and function 2.

Define a class BOX in Python with following specifications

Instance Attributes

- BoxID # Numeric value with a default value 101
- Side   # Numeric value with a default value 10
- Area  # Numeric value with a default value 0

Methods:

- ExecArea() # Method to calculate Area as
                  # Side * Side
- NewBox() # Method to allow user to enter values of
                # BoxID and Side. It should also
               # Call ExecArea Method
- ViewBox() # Method to display all the Attributes
