函数NameError [英] Functions NameError

问题描述

我一直在搞一些代码，试图创建一个工作计划的功能。但是我卡住了，想知道有人可以帮忙吗？谢谢

  class Work_plan（object）：
 def __init __（self，hours_work，work_len，work_des）：
 self.hours_work = hours_work 
 self.work_len = work_len 
 self.work_des = work_des 
 $ b work_load = [] 
 hours_worked = [] 
 hours_worked > hours_work：
 print工作太多！ 
 else：
 work_load.append（work_des）
 hours_worked.append（work_len）
 print工作已经添加到您的工作计划中！ 
 
 work_request = Work_plan（8,2，task1）
 Work_plan 
 print work_load 
  

它出现错误：
NameError：名称'work_load'未定义

解决方案你在类的 __ init __ 中定义了变量 work_load ，所以你不能访问它如果你想访问 work_load ，使它成为<$ $的对象的一个​​属性。

c $ c> Work_plan 类，并通过执行 object.work_plan

例如：

  class Work_plan（object）：
 def __init __（self，hours_work，work_len，work_des）： 
 self.hours_work = hours_work 
 self.work_len = work_len 
 self.work_des = work_des 
 
 self.work_load = [] 
 self.hours_worked = [ ] 
如果hours_worked> hours_work：
 print工作太多！ 
 else：
 self.work_load.append（work_des）
 self.hours_worked.append（work_len）
 print工作已经添加到您的工作计划中！ 
 
 work_request = Work_plan（8,2，task1）
 Work_plan 
 print work_request.work_load 
  

I have been messing around with some code, trying to create a function for work planning. However I am stuck and wondered if someone could help? Thanks

class Work_plan(object):
    def __init__(self,hours_work,work_len, work_des):
        self.hours_work = hours_work
        self.work_len = work_len
        self.work_des = work_des

        work_load = []
        hours_worked = []
        if hours_worked > hours_work:
            print "Too much work!"
        else:
            work_load.append(work_des)
            hours_worked.append(work_len)
            print "The work has been added to your work planning!"

work_request = Work_plan(8, 2, "task1")
Work_plan
print work_load

it comes up with the error: NameError: name 'work_load' is not defined

解决方案

You defined the variable work_load inside the __init__ of the class, so you can't access it outside this scope.

If you want to have access to work_load, make it an attribute for objects of Work_plan class, and the access it by doing object.work_plan

For example:

class Work_plan(object):
    def __init__(self,hours_work,work_len, work_des):
        self.hours_work = hours_work
        self.work_len = work_len
        self.work_des = work_des

        self.work_load = []
        self.hours_worked = []
        if hours_worked > hours_work:
            print "Too much work!"
        else:
            self.work_load.append(work_des)
            self.hours_worked.append(work_len)
            print "The work has been added to your work planning!"

work_request = Work_plan(8, 2, "task1")
Work_plan
print work_request.work_load
