Python的类设计 - 参数错误 [英] Class Design for Python - Parameter Error

问题描述

我正在尝试使用以下代码为员工创建一个python代码，但它会出现错误Object（）不带参数）我的目标是创建一个程序来保持跟踪组织中的员工，允许用户在简单的数据库中添加和删除员工，列出员工姓名和工号，工资并更新工资，并将所有信息读写到文本文件中。



到目前为止这是我的代码：

  class 员工： 
  员工有姓名，一个员工编号，工作年数，薪资和假期  
 
  def  __init __（self，name，StaffNumber，YearsWorked，Salary，HolidayEntitlement）：
 self._name = name 
 self._StaffNumber = StaffNumber 
 self._YearsWorked = [] 
 self._Salary = [] 
 self._HolidayEntitlem ent = [] 
 
  def  addEmployee（self）：
 text = int（input（ 输入员工姓名））
   i 在范围内（文本）：
 self._name（输入（ 输入员工姓名））
 
e =员工（  Jean Green ，  13026，  7， £12,890，  42天）
 
  print （ 员工：，e._name）
  print （ 员工：，e._StaffNumber）
  print （ 员工：， e._YearsWorked）
  print （ 员工：，e._Salary）
  print （ 员工：，e._HolidayEntitlement）

如何正确创建？

解决方案

在Python中，代码的缩进对于编译器理解你来说至关重要...在你的情况下，def __init__没有缩进，所以这不是类的一部分 - 默认的创建者没有参数...

代码应如下所示：

  class 员工：
   员工有姓名，一个员工编号，工作年数，薪水和假期 
 
   注意这里的缩进!!!   
  def  __init __（self，name，StaffNumber，YearsWorked，Salary，HolidayEntitlement）：
 self ._name = name 
 self._StaffNumber = StaffNumber 
 self._YearsWorked = [] 
 self._Salary = [] 
 self._HolidayEntitlement = [] 

I'm trying to create a python code for employees using the following code but it is coming up with an error "Object () takes no parameters) My objective is to create a program to keep track of employees in an organisation, by allowing the user to add and remove employees from a simple database listing their staff names and number, salaries and update their salaries and read and write all the information into a text file.

So far this is my code:

class Employee:
    """ Employee has name, one staff number, number of years worked, Salary and Holiday"""

def __init__(self, name, StaffNumber, YearsWorked, Salary, HolidayEntitlement):
    self._name=name
    self._StaffNumber=StaffNumber
    self._YearsWorked=[]
    self._Salary=[]
    self._HolidayEntitlement=[]

    def addEmployee(self) :
        text = int(input("Enter Employee's Name"))
        for i in range (text):
            self._name(input("Enter Employee's Name"))

e = Employee("Jean Green", "13026", "7", "£12,890", "42 days")

print ("Employee: ", e._name)
print ("Employee: ", e._StaffNumber)
print ("Employee: ", e._YearsWorked)
print ("Employee: ", e._Salary)
print ("Employee: ", e._HolidayEntitlement)

How do I create it right?

解决方案

In Python the indentation of your code is critical to the compiler to understand you...In your case def __init__ not indented so this is no part of class - the default creator takes no parameter...
The code should look like this:

class Employee:
    """ Employee has name, one staff number, number of years worked, Salary and Holiday"""
 
    """ Notice the indentation here!!! """
    def __init__(self, name, StaffNumber, YearsWorked, Salary, HolidayEntitlement):
        self._name=name
        self._StaffNumber=StaffNumber
        self._YearsWorked=[]
        self._Salary=[]
        self._HolidayEntitlement=[]
