一次只允许在 Tkinter 中选择一个单选按钮

Question

我正在尝试学习 tkinter 模块的基础知识。我制作了这个程序，我有一些问题，每个问题都有一些选项。我的选项使用单选按钮 selection 显示。我想 select 一次独立地为每个问题做一个选择。目前，当我 select 第一个选项时，每个问题的第一个选项都是 selected 但我不希望 selection 除了我正在处理的那个之外。

我的第二个问题是 selection [完成] 后，我想使用 selection 结果并将它们与答案键进行比较，看看有多少答案是正确的。如何存储用户对每个问题的回答？

输出结果：

编辑：抱歉，我也没有发布我的代码。这是我正在处理的 python 文件。

 from tkinter import *

 guessOptions =[]

 def display():
    global guessOptions
 if x.get() == 0:
    guessOptions.append("A")
 elif x.get() == 1:
    guessOptions.append("B")
elif x.get() == 2:
    guessOptions.append("C")
else:
    guessOptions.append("D")

window = Tk()
answers = ['A', 'B', 'C', 'D']
questions = ["Who invented Bulb? ",
             "Which is not passive component? ",
             "Which is not related to computer? ",
             "Opertor used for and operation? "]

options = [['A. Thomas Edison', 'B. Nikola Tesla', 'C. Albert  
           Einstien', 'D. Michael Faraday'],
           ['A. Inductor', 'B. op-amp', 'C. Capacitor', 'D. 
            Resistor'],
           ['A. RAM', 'B. SSD', 'C. Heat', 'D. Keyboard'],
           ['!', '~', '||', '&']]

x = IntVar()

for i in range(len(questions)):
    label = Label(window,
                  text=questions[i],
                  font=('Arial', 15, 'bold'))
    label.pack(anchor=W)
    for j in range(len(options)):
        checkButton = Radiobutton(window,
                                  text=options[i][j],
                                  variable=x,
                                  value=[j],
                                  padx=10,
                                  font=('Arial', 10),
                                  command=display
                                  )
        checkButton.pack(anchor=W)

window.mainloop()

问题的每组答案都需要有自己的 IntVar，您需要添加 Button 才能触发答案检查过程。我已经在下面的代码中完成了大部分工作，除了 check_answers() 函数并没有真正做任何有意义的事情，因为您没有确切指定将涉及的内容（甚至正确的选择是什么）。

from tkinter import *

guessOptions =[]

def display(x):
    global guessOptions

    if x.get() == 0:
        guessOptions.append("A")
    elif x.get() == 1:
        guessOptions.append("B")
    elif x.get() == 2:
        guessOptions.append("C")
    else:
        guessOptions.append("D")

def check_answers():
    print(f'{guessOptions=}')


window = Tk()
answers = ['A', 'B', 'C', 'D']
questions = ["Who invented bulb? ",
             "Which is not passive component? ",
             "Which is not related to computer? ",
             "Operator used for and operation? "]

options = [['A. Thomas Edison', 'B. Nikola Tesla', 'C. Albert Einstein',
            'D. Michael Faraday'],
           ['A. Inductor', 'B. Op-amp', 'C. Capacitor', 'D. Resistor'],
           ['A. RAM', 'B. SSD', 'C. Heat', 'D. Keyboard'],
           ['!', '~', '||', '&']]

variables = []
for i in range(len(questions)):
    label = Label(window, text=questions[i], font=('Arial', 15, 'bold'))
    label.pack(anchor=W)

    var = IntVar(value=-1)
    variables.append(var)  # Save for possible later use - one per question.

    def handler(variable=var):
        """Callback for this question and group of answers."""
        display(variable)

    for j in range(len(options)):
        checkButton = Radiobutton(window, text=options[i][j], variable=var,
                                  value=j, padx=10, font=('Arial', 10),
                                  command=handler)
        checkButton.pack(anchor=W)

comp_btn = Button(window, text="Check Answers", command=check_answers)
comp_btn.pack()

window.mainloop()
