python - 继承函数后如何给它更多的参数

Question

我为我的 masters_student 类继承了一个 student 类，并且所有功能都按预期工作，但我想给我的 masters_student 类另一个参数称为Age。

我怎样才能做到这一点？

class masters_student(student , age):
    self.age = age
        def qualify(self):
            if self.Gpa > 3.0 :
                print("You qualify for the masters Programme")
            else:
                print("you dont qualify for Masters programme")

然后显示错误

class student:
    def __init__(self, name, major, Gpa, loan):
        self.name = name
        self.major = major
        self.Gpa = Gpa
        self.loan = loan

    def On_honour_roll(self):
        if self.Gpa >= 3.5:
            return True
        else:
            return False


class masters_student(student):
    def qualify(self):
        if self.Gpa > 3.0 :
            print("You qualify for the masters Programme")
        else:
             print("you dont qualify for Masters programme")

Answer 1

这里是一些关于 [ https://rhettinger.wordpress.com/2011/05/26/super-considered-super/][super] 的文档。

你需要告诉Python如何在父类之后实例化你的子类。

class master_student(student):

def __init__(self, name, major, Gpa, loan, age):
    super(student, self).__init__(name, major, Gpa, loan)
    self.age = age

这应该有效。
