Python 在用户输入后，在重复函数中保存条目的值
嗨，我叫克里斯，我的代码有点乱 也是我第一次问问题。所以我的问题是我有 一个按钮，每次按下时将运行一个功能，此按钮 函数在用户所在位置的旁边创建3个条目 希望在每个输入框中输入适当的信息 问题是我增加了一个按钮，当按下按钮时，应该会拉动按钮 值，并将其保存到稍后我想保存的位置 用它来做方程式。我的问题是，既然我在重复 条目的，他们不是唯一的每一次，而是一个克隆，所以我不能 似乎告诉程序查找每个条目，因为它们是 彼此，或者至少我是这么想的 我尝试了许多不同的方法来保存这些值，下面是每种方法 我尝试过的方法： 下面是我的代码中没有代码的部分，我尝试保存 价值： 如果您需要我乐意帮助的任何其他信息，我还有一个 GitHub如果需要的话，我也可以在必要时提供我的全部代码， 我正在使用pycharmPython 在用户输入后，在重复函数中保存条目的值,python,tkinter,Python,Tkinter,嗨，我叫克里斯，我的代码有点乱 也是我第一次问问题。所以我的问题是我有 一个按钮，每次按下时将运行一个功能，此按钮 函数在用户所在位置的旁边创建3个条目 希望在每个输入框中输入适当的信息 问题是我增加了一个按钮，当按下按钮时，应该会拉动按钮 值，并将其保存到稍后我想保存的位置 用它来做方程式。我的问题是，既然我在重复 条目的，他们不是唯一的每一次，而是一个克隆，所以我不能 似乎告诉程序查找每个条目，因为它们是 彼此，或者至少我是这么想的 我尝试了许多不同的方法来保存这些值，下面是每种方法 我尝试
我添加这些只是为了让你知道该做什么，或者该做什么，这只是如何继续的方法之一 基本上，只需在
调用中创建两个空列表，然后将这些条目小部件附加到前面创建的列表中，如：
def __init__(self):
.....#same bunch of code
self.lst1 = []
self.lst2 = []
然后在new_row（）
方法的末尾，说：
def new_row():
....#same bunch of codes
self.lst1.append(entry_Box)
self.lst2.append(entry_Box2)
现在通过这种方式访问条目小部件，比如说print（lst1[0].get（））
。这将返回第一列第一个框中的内容print（lst2[0].get（））
将返回第二列第一个框中的内容，这样，您可以得到矩阵类型排列的模式，并且可以轻松地获得如下值
虽然我建议删除条目小部件的绑定，因为它们稍后会给您带来问题，但是如果您正在使用tkinter条目小部件创建占位符，请看一看。虽然课程并不完美，但仍能完成任务
还要记住名称
和金额
都是无用的，因为它们都是无
，所以使用它们是没有意义的。你在帖子中再次重复相同的代码，在你解释不同的方法时，把代码去掉，只包括重要的内容。也许可以尝试将其添加到列表中，并在列表中使用索引来调用所需的项目？@ChrisBoss我不会撒谎，看起来你的代码有点问题，但我可以试着帮你。第一个错误是因为变量“name”仅在函数“new_row”的作用域中可用。首先，我建议您将init函数放在类中的第一位，并将要使用的所有变量列在其中，即self.name=entry\u框。插入（0，“收入名称”）
，然后使用app.name
访问它。还有，为什么你在课堂上有返回语句？我补充了一个答案，让我知道它的工作非常感谢@CoolCloud，几个月的工作，结束在望，谢谢。
