Question

我必须制作一个代码，该代码将生成一个GUI，显示三个类的测试结果，所有信息都将存储在一个文件中。我试图做代码我可以制作GUI和单选按钮，这一切都有效，但是得到一个按钮，允许你把文本框中的内容按字母顺序排列。

from tkinter import *
root = Tk()
root.title("Test scores")
root.geometry("500x300")

app = Frame(root)
app.grid()
test1 = open("names.txt","r")
test2 = open("score.txt","r")
test3 = open("class.txt","r")
class Application(Frame):
    def __init__(self, master):
        super(Application, self).__init__(master)
        self.grid()
        self.create_widgets()
    def create_widgets(self):
        Label(self,
              text = "Which class "
              ).grid(row = 0,column = 0, sticky = W)
        Label(self,
              text = "Select a class"
              ).grid(row = 1, column = 0, sticky = W)
        self.choose = StringVar()
        self.choose.set(None)
        Radiobutton(self,
               text = "Class 1",
               variable = self.choose,
               value = test1.read(), 
               command = self.update_text
               ).grid(row = 2, column = 0, sticky = W)
        self.second = BooleanVar()
        Radiobutton(self,
               text = "Class 2",
               variable = self.choose,
               value = test2.read(),     
               command = self.update_text
               ).grid(row = 3, column = 0, sticky = W)
        self.third = BooleanVar()
        Radiobutton(self,
               text = "Class 3",
               variable = self.choose,
               value = test3.read(),     
               command = self.update_text
               ).grid(row = 4, column = 0, sticky = W)
        self.bttn = Button(self)
        self.bttn["text"] = "Alphabetical"
        self.bttn["command"] = self.update_order
        self.bttn.grid(row = 4, column = 1, sticky = W)

        self.results_txt = Text(self, width = 40, height = 5, wrap = WORD)
        self.results_txt.grid(row = 5, column = 0, columnspan = 3)

    def update_text(self):
        likes = ""
        likes += self.choose.get()
        self.results_txt.delete(0.0, END)
        self.results_txt.insert(0.0, likes)

    def update_order(self):
        sortfile = open("sorted1.txt","w")
        for line in sorted(self.results_txt, key = str.lower):
            sortfile.write(line)



app = Application(root)
root.mainloop()

到目前为止，这是我的代码。

我试图对它进行排序，但它不起作用这是我尝试的代码，因为我在网上查看并看到了这个

def update_order(self):
        str(sorted(self.results_txt, key=lambda student: student[2]))

我将如何排序文件行所以如果第一行有“名字”“第一分”“第二分”“第三分” 然后在第二行“不同的名字”“第一个得分”“第二个得分”“第三个得分” 你将如何按字母顺序按行中的名称对其进行排序。我需要将每个分数放在不同的文件上吗？

我如何订购文件行？
