Member functions

Member Functions returning value

If we want to use our member function in expression.
Then our member function must return a value using return statement.
The return statement returns value at point from where function is call.

Syntax:

def function-Name(self,argument1,argument2,...):
  Statements
  ----------
  return value

#Program to create 2 rectangles a and b of size 5 x 7 and 10 x 20. Display area, perimeter of a and area of b.

Design a class Rectangle

Data members

Length
Breadth

Member Functions

Area()
setdimension(x,y)

class Rectangle :
  def setDimension(self,x,y):
    self.length = x
    self.breadth = y
  def area(self):
    a = self.length*self.breadth
    return a
 
a = Rectangle()
b = Rectangle()
a.setDimension(5,7)
b.setDimension(10,20)
z = a.area()+b.area()
print("Total Area is ",z)
print("Area of a is ",a.area())
print("Area of b is ",b.area())

Total Area is 235
Area of a is 35
Area of b is 200

#WAP to create 2 Worker type of objects : a ( name=Raja , wages=500 , wdays=5 ) b ( name=Gaja , wages=400, wdays=8 ) Showdata and payment of both workers as well as total payment.

Design a class Worker

Data members

name
wages
wdays

Member Functions

setData(n,w,d)
payment()
showdata()

class worker:
  def setData(self,n,w,d):
    self.name=n
    self.wages=w
    self.wdays=d
  def showData(self):
    print("Name is ",self.name)
    print("Wages is ",self.wages)
    print("Wdays is ",self.wdays)
  def payment(self):
    p=self.wages*self.wdays
    return p

a=worker()
b=worker()
a.setData("Raja",500,5)
b.setData("Gaja",400,8)
a.showData()
print("Payment is ",a.payment())
b.showData()
print("Payment is ", b.payment())
z = a.payment() + b.payment()
print("Total Payment is ",z)

Name is Raja 
Wages is 500
Wdays are 5
Payment is 2500
Name is Gaja
Wages is 400
Wdays are 8
Payment is 3200
Total Payment is 
5700

#WAP to create 2 set type of objects : a = { 2 , 5 , 3 } b = { 6 , 10 , 4 } Display sum both sets as well as mean of b.

Design a class Set

Data members

Member Functions

setData(x,y,z)
sum()
mean()

class Set:
  def setData(self,x,y,z):
    self.n1=x
    self.n2=y
    self.n3=z 
  def sum(self):
    s=self.n1+self.n2+self.n3
    return s 
  def mean(self):
    m=self.sum()/3
    return m

a=Set()
b=Set()
a.setData(2,5,3)
b.setData(6,10,4)
z = a.sum() + b.sum()
print("Total Sum is ",z)
print("Mean of b is ",b.mean())

Total Sum is 30
Mean of set b is 
6.666667
