Python Tkinter。如何通过标签中的按钮存储条目

我真的需要一些代码方面的帮助。我不希望你为我写，因为这是一个学校的项目，但我真的迷失了方向，需要帮助

我正在编写的代码是某种生产系统。
它实际上不需要能够将任务发送到任何地方，因为这只是一个想象中的场景

代码必须由三个文件组成：data.py、model.py和gui.py

• Gui可以访问另外两个文件
• 数据只能访问模型
• 模型无法访问其他两个

我的老师写了一些代码，我继续讲下去。部分文本为丹麦语，但大多数评论为英语。 代码如下

data.py

from model import *

class Data(object):

def __init__(self):
    self.units = []
    self.finished_tasks = []

def __str__(self):
    result = "These tasks have been finished: "
    for i in self.finished_tasks:
        result += str(i)
    return result

def task_done(self, unit):
    done_task = unit.task_done()
    if done_task != None:
        #TODO: add to list of finished tasks
        pass

def add_task(self, name, amount, unit):
    s = Springroll_task(name, amount)
    unit.add_to_queue(s)

def read_from_database(self):#doesn't actually read from db..
    self.units.append(Production_unit("maskine1"))
    self.units.append(Production_unit("maskine2"))

    self.add_task("Miniruller", 100, self.units[0])

所以现在看起来是这样的：

我需要能够做的是在底部的两个条目小部件中输入信息，然后将它们放入上面4个标签小部件中的一个，从顶部开始，然后放入队列中，这应该在我按下按钮add_时发生，但现在似乎不见了。
之后，当按下“opgivedafslutte”按钮时，我需要将任务存储在数据文件中

我真的希望有人能帮助我

我用一些建议编辑了它，我想我现在正在调用正确的self.eq1_ent.get（）。我再也不会出错了，现在我真的不知道如何让它做我想做的。 编辑2：我正在慢慢地得到一些东西，所以我对model.py和gui.py进行了更改。。。 现在看起来是这样的：

---

自身。未定义eq1

。您有

self.q1\u lbl

和

self.eq1\u ent

要访问标签，请使用

self.q1\u lbl

要能够将文本设置为标签，请按以下方式创建它们：

self.var = StringVar()
self.unit_name_lbl = Label(self, textvariable=self.var)

例如，从

redraw（）

可以将

'text'

设置为

self.unit\u name\u lbl

如下：

self.var.set（'text'）

• 检查您是否遗漏了

  d中的
  self
  。添加任务（n，a，单位）

• 当您执行

  command=mod.add_to_queue（self.ea1_ent.get（））

  时，将直接调用

  mod.add_to_queue

  函数，如果您想在用户按下按钮时将参数传递给此函数，可以使用

  lambda

  ：

  command=lambda: mod.add_to_queue(self.ea1_ent.get)
  

---

自身。未定义eq1

。当您调用

Entry.get（）

时，您有

self.q1\u lbl

和

self.eq1\u ent

，它将获得确切时刻的内容。由于您在创建空条目后立即调用

.get（）

，因此只会得到空字符串。谢谢您的回答，其他人将其作为注释回答，但已将其删除，因此我已更正。我仍然不知道如何将标签amount1、Amount2以及所有q1-q3和a1-a3更改为我在条目中所写的内容。
