我问这个问题是为了帮助遇到同样问题的其他人 - 这就是没有示例代码的原因.这个问题困扰了我好几个小时，我用这个问题来教别人.请不要把它当作一个真正的问题来评价——答案才是最重要的.

I asked this question to help others with the same problem - that is the reason why there is no example code. This issue had been troubling me for hours and I used this question to teach others. Please do not rate it as if it was a real question - the answer is the thing that matters.

推荐答案

要从文本框中获取 Tkinter 输入，您必须向普通的 .get() 函数添加更多属性.如果我们有一个文本框 myText_Box，那么这就是检索其输入的方法.

To get Tkinter input from the text box, you must add a few more attributes to the normal .get() function. If we have a text box myText_Box, then this is the method for retrieving its input.

def retrieve_input():
    input = self.myText_Box.get("1.0",END)

第一部分，"1.0" 意味着输入应该从第一行，字符零(即:第一个字符)读取.END 是一个导入的常量，它被设置为字符串 "end".END 部分表示一直读到文本框的末尾.唯一的问题是它实际上为我们的输入添加了一个换行符.因此，为了修复它，我们应该将 END 更改为 end-1c(感谢 Bryan Oakley) -1c 删除 1 个字符，而 -2c 表示删除两个字符，依此类推.

The first part, "1.0" means that the input should be read from line one, character zero (ie: the very first character). END is an imported constant which is set to the string "end". The END part means to read until the end of the text box is reached. The only issue with this is that it actually adds a newline to our input. So, in order to fix it we should change END to end-1c(Thanks Bryan Oakley) The -1c deletes 1 character, while -2c would mean delete two characters, and so on.

def retrieve_input():
    input = self.myText_Box.get("1.0",'end-1c')
