Question

好吧我是OOP的新手，我的问题是我有这个父类，并且它有一个方法信息。我想在该方法中为其子类重用该方法中的两个print语句命名并向其添加更多信息。但我无法让它工作

class company:

    def __init__(self, fName, lName, salary):

        self.fName = fName
        self.lName = lName
        self.salary = salary

    def info(self):
        print("Name:", self.fName, self.lName)
        print("Salary:", self.salary)

class programmers(company):
    def __init__(self, fName, lName, salary, progLang):

        super().__init__(fName, lName, salary)
        self.progLang = progLang

    def info(self):
        print("Programming language:", self.progLang)

programmer1 = programmers("John", "Doe", 1000, "Python")
programmer1.info()

我想过只是重写我想要重用的代码行，但我认为这样可以解决OOP问题。

我正在寻找这种输出......

Name: John Doe
Salary: 1000
Programming language: Python

我正在使用Python 3

提前致谢！

试试以下代码。您的父类应继承自"object"。 super仅适用于new style classes

class company(object):

    def __init__(self, fName, lName, salary):

        self.fName = fName
        self.lName = lName
        self.salary = salary

    def info(self):
        print("Name:", self.fName, self.lName)
        print("Salary:", self.salary)

class programmers(company):
    def __init__(self, fName, lName, salary, progLang):

        super(programmers, self).__init__(fName, lName, salary)
        self.progLang = progLang

    def info(self):
        super(programmers, self).info()
        print("Programming language:", self.progLang)

programmer1 = programmers("John", "Doe", 1000, "Python")
programmer1.info()
