Create a class of name arithematic logic operator. Over load the operator
An example of an ArithmeticLogicOperator class that overloads the +, -, *, and / operators is
class ArithmeticLogicOperator:
def __init__(self, value):
self.value = value
def __add__(self, other):
return self.value + other.value
def __sub__(self, other):
return self.value - other.value
def __mul__(self, other):
return self.value * other.value
def __truediv__(self, other):
return self.value / other.value
How does this work?You can create instances of the ArithmeticLogicOperator class and perform arithmetic operations using the overloaded operators.
he ArithmeticLogicOperator class takes a value as input during initialization.
The overloaded operators allow you to perform arithmetic operations between instances of the class, returning the desired result.
