How to change class instance?

Question

This is my Class, below i made two instances h1 and h2, each has different names, then i want to add h2 to h1 like h1.money + h2.money then we supposed to get h1.money = 100. but i dunno how to do that.

class Bank:
    def __init__(self, name):
        self.name = name
        self.money = 50

    def __add__(self, other):
        if isinstance(other, Bank):
            self.money = self.money + other.money
            return Bank(self.name)

    def info(self):
        print(self.money)


h1 = Bank('Br1')
h2 = Bank('Br2')
h1 = h1 + h2

print(h1.name, h1.money)

output: Br1 50

Answer 1

After you modify the money, you should return self.

class Bank:
    def __init__(self, name):
        self.name = name
        self.money = 50

    def __add__(self, other):
        if isinstance(other, Bank):
            self.money = self.money + other.money
            # return Bank(self.name)
            return self

    def info(self):
        print(self.money)


h1 = Bank('Br1')
h2 = Bank('Br2')
h1 = h1 + h2

print(h1.name, h1.money)
# Br1 100
