python - Python 中的类及其实现

Question

我正在尝试创建一个可以导入我的PersonWorker课程的 Python 脚本（WageEarner）。我需要它来提示一个人的名字、姓氏和电话号码，因为它将PersonWorker使用用户提供的信息创建一个对象。我需要它来提示用户一周的工作时间和工资率。它将通过调用该对象的方法打印出PersonWorker对象和每周工资。getWeeksPay我是 Python 新手，所以我不熟悉如何做到这一点。

这是我的PersonWorker课：

class PersonWorker:

    def _init_(self, firstName, lastName, phoneNo, rate=0):
        self.firstName= firstName
        self.lastName= lastName
        self.phoneNo= phoneNo
        self.rate= rate
    def getFirstName(self):
        return self.firstName
    def getLastName(self):
        return self.lastName
    def getPhoneNo(self):
        return self.phoneNo
    def getWeeksPay(self,hours):
        if rate is 0: raise Exception("Rate not set")
        return hours*self.rate
    def _str_(self): 
        stringRep = "First Name: " + self.firstName + "\n"
        stringRep = "Last Name: " + self.lastName + "\n"
        stringRep = "Phone Number : " + self.phoneNo + "\n"
        return stringRep
