如何在Tkinter文本小部件中打印字典项？

Question

我已经创建了一个程序，它允许用户输入个人的用户名，并为特定的名称分配特定的数字（点数）

因此，所有数据都存储在字典中，如下所示：

{'Username': 0, 'Username2': 0, .... and so on} 

当用户点击“结果”按钮时，新窗口出现，我可以看到这个字典打印在终端上。但是，现在我想在新Tkinter窗口的文本框中打印此词典的数据。我试图这样做，但文本框中没有显示任何内容

或者我应该使用标签小部件这样做

如何解决这个问题

我想我应该在这里做些改变，但我不知道具体是什么

class resultPage(ttk.Frame):
    def __init__(self, parent, controller):
        self.controller = controller
        ttk.Frame.__init__(self, parent)
        self.userEntry()

    def userEntry(self):
        preInd = Label(self, text="Points of Individuals:", font="Arial 20")
        preInd.grid(row=0, column=0, pady=10, padx=10)
        self.inputInd = Text(self, height=10, width=15)
        self.inputInd.grid(row=1, column=0)

        for i in IndividPoints:
            self.inputInd.insert(END, i + '\n')


if __name__ == '__main__':
    Individuals = []
    IndividPoints = {}
    app = CollegeApp()
    app.geometry("800x500")
    app.resizable(False, False)
    app.title('Points Counter')
    app.mainloop()

以下是我的代码的工作部分：

            frame = F(self.container, self)
            self.frames[F] = frame
            frame.grid(row=0, column=0, sticky="nsew")
        self.show_frame(IndividPage)

        frame.tkraise()

    def show_list_frame(self):
        list_frame = counterPage(self.container, self)
        list_frame.grid(row=0, column=0, sticky="nsew")

这是否解决了您的问题（对您说不起作用的代码所做的更改）：

import tkinter.ttk as ttk
from tkinter import Tk, END, Label, Text


class resultPage(ttk.Frame):
    def __init__(self, parent, controller):
        self.controller = controller
        ttk.Frame.__init__(self, parent)
        self.userEntry()

    def userEntry(self):
        preInd = Label(self, text="Points of Individuals:", font="Arial 20")
        preInd.grid(row=0, column=0, pady=10, padx=10)
        self.inputInd = Text(self, height=10, width=15)
        self.inputInd.grid(row=1, column=0)

        for i in IndividPoints:
            self.inputInd.insert(END, i + '\n')


if __name__ == '__main__':
    Individuals = []
    IndividPoints = {'Username': 0, 'Username2': 0}
    app = Tk()
    app.geometry("800x500")
    app.resizable(False, False)
    app.title('Points Counter')
    resultPage(app, None).pack()
    app.mainloop()

首先，我向各个点添加了值，第二，我实际打包了帧，以便显示在屏幕上（您必须相应地进行调整，但此示例有效）
