我如何编写一个子类并在Python 3.7中添加变量？ [英] How do I write make a sub class and add variable to that in Python 3.7?

问题描述

我编写了一个子类，但我很困惑如何在类和子类之间建立连接。我正在尝试打印员工和经理的信息，但我不能。如果有人能帮助我，我将不胜感激。

I have written a subclass but I am confused how I can make a connection between the class and subclass. I am trying to print the information of the the employee and the manager but I could not. I would be grateful if someone can help me.

class Information:
    def __init__(self,first,last,pay):

        self.first = first
        self.last = last
        self.pay = pay


    def rise(self,bonus):
        self.pay = self.pay + bonus

    def __str__(self):
        return "%s and %s and has a balance of %s" % (self.first,self.last,self.pay)

if __name__ == "__main__":
    emp1 = Information("tom","jerry",999)
    emp1.rise(89)
    print (emp1)


from information import Information
class Manager(Information):
    def __init__(self):
        Information.__init__(self)
        self.shift = shift
        self.time = time
    def __str__(self):
        return Information.__str__(self)+str(self.time) + self.shift

    if __name__ == "__main__":
        information = Information()
        print (information)
        information.time(9)
        information.title(morning)
        print (Information)

谢谢。



我尝试了什么：



我试图在两个不同的文件中编写类和子类，并希望通过导入连接它们但是没有用。

Thank you.

What I have tried:

I have tried to write the class and sub class in two different files and wanted to connect them by import but that did not work.

推荐答案

在子类中，您使用错误的参数和不存在的函数名称调用Information类。请查看 9。类 - Python 3.7.2文档 [ ^ ]。

In your subclass you are calling the Information class with the wrong parameters, and non-existent function names. Take a look at 9. Classes — Python 3.7.2 documentation[^].

class Information:
    def __init__(self,first,last,pay):

        self.first = first
        self.last = last
        self.pay = pay


    def rise(self,bonus):
        self.pay = self.pay + bonus

    def __str__(self):
        return "%s and %s and has a balance of %s" % (self.first,self.last,self.pay)



from information import Information
class Manager(Information):
    def __init__(self,shift,time):
        Information.__init__(self)
        self.shift = shift
        self.time = time
    def __str__(self):
        return Information.__str__(self)+str(self.time) + self.shift

if __name__ == "__main__":
    emp = Information("tom","jerry",999)
    emp.rise(89)
    managerr = Manager("morning",9)
    print (managerr)
    
    
    print (emp1)
