我正在使用 Python 构建打字速度游戏，并且在绑定一些小部件时遇到问题。
我从 Youtube 上获得了以下视频的灵感：https://www.youtube.com/watch?v=ktv8nNhTDu4&ab_channel=CodingLifestyle4u
我想为用户提供视觉帮助，这样，每当他/她输入某些内容时，按下的键就会在虚拟键盘（使用标签创建）上以蓝色突出显示。
我对此很陌生，这是我的投资组合的第一个项目的一部分。
抱歉，如果代码不完整，如果我尝试全部输入，Stackoverflow 会说我的代码看起来像垃圾邮件。
我感谢您提供的任何帮助。
找到下面的代码。
Pd。我还没有完成使按钮工作的功能。我被标签的绑定困住了，我真的需要理解为什么它不起作用。

您的问题表明用户输入的键应该突出显示。那为什么要打开并读取文本文件呢？
假设您想突出显示用户按下的键，我在这里给出了代码的特定部分。了解想法并根据您的要求修改其余代码。
您不需要为所有键创建
dict'<key>'from tkinter import *
def highlight_text(event):
# get the key pressed by the user
key_pressed = event.keysym
# configure the widget typed_txt with text being key_pressed and fg being blue
typed_txt.config(text = key_pressed, fg = 'blue')
root = Tk()
root.geometry("1200x800+500+100")
lbl_txt = Label(root, text = 'Type Text', font="arial 14 bold", fg="black")
lbl_txt.pack()
# A text box where the user types the text
user_text = Text(root, width = 100, height = 10)
user_text.pack()
# Bind the widget user_text with '<key>' and the function highlight_text
user_text.bind('<Key>', highlight_text)
#create a label for highlighting the text without the text parameter
# Ensure that the font-size being very big
typed_txt = Label(root, font="arial 200 bold")
typed_txt.pack()
root.mainloop()
