Python Program to Convert Km to Meter using Operator Overloading

class Distance_m:
    def __init__(self, m):
        self.m=m
    def display(self):
        print("Distance in metre is :", self.m)
    def mts(D):
        return D.km*1000
class Distance_km:
    def __init__(self, km):
        self.km=km
    def display(self):
        print("Distance in KM is :", self.km)
def km(D):
    return D.m/1000
Dm=Distance_m(7000)
Dm.display()
print("Distance in KM is :", km(Dm))
