一次只允許在Tkinter中選擇一個單選按鈕

我正在嘗試學習該tkinter模塊的基礎知識。我制作了這個程式，我有一些問題，每個問題都有一些選項。我的選項使用單選按鈕選擇顯示。我想為每個問題一次選擇一個選項。目前，當我選擇第一個選項時，每個問題的第一個選項都會被選中，但我不希望選擇我所在的選項。

我的第二個問題是，一旦選擇[進行]，我想使用選擇結果并將它們與答案鍵進行比較，看看有多少答案是正確的。如何存盤用戶對每個問題的回答？

輸出結果：

編輯：很抱歉也沒有發布我的代碼。這是我正在處理的python檔案。

 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'],

uj5u.com熱心網友回復：

問題的每組答案都需要自己的答案IntVar，您需要添加一個Button來觸發答案檢查程序。我已經在下面的代碼中完成了大部分作業，除了這個check_answers()函式并沒有真正做任何有意義的事情，因為你沒有具體說明會涉及什么（甚至是正確的選擇是什么）。

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()
