好的，所以我做了大约10天的搜索，我陷入了困境，所以我转向社区寻求帮助。 我使用python 3.6和tkinter作为用户界面。 我想要完成的基本内容是我有一个文件，我打开并在文件中搜索一个单词并插入单词所在的所有行。 我的问题是它只插入它找到的第一行，我需要它插入它找到的所有行。对于湿编码我很抱歉，一旦我有功能，我就会把它弄干净
这是我的代码示例（它不是完整的东西，但它应该给你足够的信息，我想要完成的事情）：

答案 0 :(得分：0)
编辑：
我对您的代码进行了一些更改。
有太多标志与你设置的方式有关。
由于我不能100％确定您要完成的任务，我已经在您的代码方面取得了进展。
以下是您的代码的编辑版本。 我还在我的最后创建了一个文本文件来测试，并且接缝已经工作了，所以请告诉我这是否接近你试图做的事情。
一些注意事项：
第一天我把所有东西都搬到了一个班级。如果没有一些重大改变，你设置它的方式就不会起作用。第二，我需要将self.添加到您的许多变量中，因为它们是我们需要在类中进行交互的变量。
第3次我改变了他们从输入框中获取数据的方式。你这样做的方式就是不行，所以我通过在条目变量中添加.get()函数来简化它。
Tk()窗口启动的方式很奇怪。我改变了root的创建方式以及如何将它传递到类中。这种接缝对我来说更有意义。
使用IMO要好得多。
让我知道你还需要解释哪些部分，我会根据需要更新我的答案。
更新
稍微更改while open语句。您不需要重新创建文本框并重新配置它以进行循环，这不是很好，并且会阻止您看到多个项目。此外，我不相信你可以有一个我从未尝试过的多线标签。让我们把它改成一个文本框，这应该做我们需要的。
