# Account
# Create a class called Account. Upon initialization, it should receive an id, a balance, and a pin (all numbers).
# The pin and the id should be private instance attributes, and the balance should be a public attribute.
# Create two public instance methods:
# •	get_id(pin) - if the given pin is correct, return the id, otherwise, return "Wrong pin"
# •	change_pin(old_pin, new_pin) - if the old pin is correct, change it to the new one and return "Pin changed", otherwise return "Wrong pin"

    def get_id(self, pin):
        if pin == self.__pin:
            return self.__id
        return "Wrong pin"
