Python program to Overload operators +, – and >=
Write a class Money with attributes Rupees and Paise. Overload operators + (addition of objects), – (subtraction of objects), and >=(comparing objects) so that they may be used on two objects. Also write functions so that a desired amount of money can be either added, subtracted from Money.

Source Code to Overload operators +, – and >= in Python
class Money:
def __init__(self):
self.R = 0
self.P = 0
def setValue(self, R, P):
self.R = R
self.P = P
def __add__(self, M):
Temp = Money()
Temp.R = self.R + M.R
Temp.P = self.P + M.P
if (Temp.P>=100):
Temp.P = Temp.P - 100
Temp.R = Temp.R + 1
return Temp
def __sub__(self, M):
Temp = Money()
Temp.R = self.R - M.R
Temp.P = self.P - M.P
if (Temp.P<0):
Temp.P = Temp.P + 100
Temp.R = Temp.R - 1
return Temp
def __ge__(self, M):
if (self.R > M.R or (self.R == M.R and self.P > M.P)):
return 1
else:
return 0
def display(self):
print ("Rs.", self.R, "Paisa", self.P)
m1 = Money()
m2 = Money()
m3 = Money()
m1.setValue(15, 50)
m1.display()
m2.setValue(10, 60)
m2.display()
m3 = m1 + m2
m3.display()
m3 = m1 - m2
m3.display()
if(m1>=m2):
print ('M1')
else:
print("M2")Output:
Case 1:
Rs. 15 Paisa 50
Rs. 10 Paisa 60
Rs. 26 Paisa 10
Rs. 4 Paisa 90
M1
