def apply_operation(x, operation):
    def inner(y):
        return operation(x, y)

    return inner


# hint：使用lambda表达式完成operation
add_five = apply_operation(5, _________)
print(add_five(_________))

# output：8

class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age

    def birthday(self):
        self.age += 1
        print(f"Happy {self.age} birthday, {self.name}!")


class Mylove(Person):
    def __init__(self, person, gender):
        if isinstance(person, Person):
            _____.__init__(person.name, person.age)
            self.gender = gender
        else:
            print("found the one first")
            return

    def _____(self):
        self.age += 1
        print(f"Happy {self.age} birthday, mylove \(* ~ *)/")


ta = _____("Someone", 20)
