我正在使用Python 3中的类，我很难用它们。我这里有两个程序（一个是导入另一个） 这个想法是你正在制作一份员工清单，你有三类员工每小时，薪水和志愿者。
我似乎在每个课程中都遇到了show_pay的问题。我也知道在我的Salary类中，我试图将一个字符串除以整数，但是我编写代码的方式我不太清楚如何绕过它。 我的每小时课程似乎没有打印到列表中。
提前谢谢你。我真的很困惑，我正试图通过这个项目。
第一个项目（员工）
#set global constant
SHIFT_2 = 0.05
SHIFT_3 = 0.10
#person class
class Person:
#initialize name, ID number, city
def __init__(self, name, ID, city):
self.__ID = ID
self.__name = name
self.__city = city
#display employee name
def show_person(self):
print('Name:', self.__name)
print('ID:', self.__ID)
print('City:', self.__city)
#display salary
def show_pay(self):
print('I make lots of money')
#return formatting
def __str__(self):
name_string = '(My name is ' + self.__name +')'
return name_string
# Hourly employee class
class Hourly(Person):
#initialize method calls superclass
def __init__(self, name, ID, city, base_pay, shift):
Person.__init__(self, name, ID, city)
self.__base_pay = base_pay
self.__shift = shift
#show_pay overrides the superclass and displays hourly pay rates
def show_pay(self):
if self.__shift == 1:
print('My salary is ', self.__base_pay)
elif self.__shift == 2:
print('My salary is ', (self.__base_pay * SHIFT_2) + self.__base_pay)
elif self.__shift == 3:
print('My salary is ', (self.__base_pay * SHIFT_3) + self.__base_pay)
#salary employee class
class Salary(Person):
#intialize method calls superclass
def __init__(self, name, ID, city, ann_salary):
Person.__init__(self, name, ID, city)
self.__salary = ann_salary
#show pay overrides superclass and displays salary pay rates
def show_pay(self):
print('I make ', self.__salary)
print('which is ', self.__salary // 26, 'every two weeks.')
#volunteer employee class
class Volunteer(Person):
def __init__(self, name, ID, city):
Person.__init__(self, name, ID, city)

您输入的薪水是一个字符串。转换它。
ann_salary = int(input('Enter employee annual salary: '))
