Python 元组循环（我想）

我有这个测试代码，但只有第一个问题出现。我可以回答第一个问题，分数会相应调整，但下一个问题不会出现。我尝试过研究元组循环，并尝试过使用我的代码，但没有效果。我是一个Python新手，希望能得到一些帮助。我已经花了好几个小时了相信我

from tkinter import *

root = Tk()
root.title("End of year exam")

score = 0

def submit_button_clicked():
    global score
    global questions

    score = 0
    if answer.get() == questions[0][1]:
        score+=1
    else:
        score = score
    scoretxt.config(text = "Your score is: {}".format(str(score)))


questions =[("What does 13 + 5 = ?","18"),("What does 12 + 8 = ?","20"),("What does 19 + 6 = ?","25"),("What does 17 + 15 = ?","32")]

Label(root,text = "Question : ",bg ="light grey").grid(row = 0,column = 0, sticky = W)
question=Label(root,bg = "light green",text= questions[1][0], width = 38)
question.grid(row =1,column=0)

Label(root,text = "Answer: ",bg = "light grey").grid(row = 2, column = 0, sticky = W)
answer = Entry(root,bg ="white",width = 45, justify = CENTER)
answer.grid(row = 3,column=0)

scoretxt = Label(root,text ="Your score is:",bg = "light green", width = 38)
scoretxt.grid(row = 10,column = 0, sticky = W)

### make a submit button
Button(root,text= "Submit",bg = "light grey",command = submit_button_clicked).grid(row = 4,column = 0, sticky = W)

root.mainloop()

这应该行得通。我在函数

submit\u button\u clicked（）

中添加了

try

语句，因此如果问题是最后一个问题，它仍会更新分数。如果你通读代码，你会看到我改变了什么。如果你不明白，就让我说不。祝你今天愉快

from tkinter import *

root = Tk()
root.title("End of year exam")

score = 0

questions =[("What does 13 + 5 = ?","18"),("What does 12 + 8 = ?","20"),("What does 19 + 6 = ?","25"),("What does 17 + 15 = ?","32")]

current_question = 0

def submit_button_clicked():
    global score
    global questions
    global current_question

    if answer.get() == questions[current_question][1]:
        score += 1
        current_question += 1
        try:
            question.config(text=questions[current_question][0])
        except:
            pass
        answer.delete(0, 'end')
    scoretxt.config(text = "Your score is: {}".format(str(score)))




Label(root,text = "Question : ",bg ="light grey").grid(row = 0,column = 0, sticky = W)
question=Label(root,bg = "light green",text=questions[current_question][0], width = 38)
question.grid(row =1,column=0)

Label(root,text = "Answer: ",bg = "light grey").grid(row = 2, column = 0, sticky = W)
answer = Entry(root,bg ="white",width = 45, justify = CENTER)
answer.grid(row = 3,column=0)

scoretxt = Label(root,text ="Your score is:",bg = "light green", width = 38)
scoretxt.grid(row = 10,column = 0, sticky = W)

### make a submit button
Button(root,text= "Submit",bg = "light grey",command = submit_button_clicked).grid(row = 4,column = 0, sticky = W)

root.mainloop()

“只有第一个问题出现”。。嗯，可能是因为你只做

问题[1][0]

？我知道问题[1][0]会让它显示第一个问题，但我不确定如何修改代码以便它显示下一个问题，比如，当单击提交按钮时。我不知道如何更改Tkinter中的标签文本，但您可以保留一个全局变量，用于您当前所问的问题。当您正确回答问题时，您可以增加该计数器，并重置标签中的文本。非常感谢您的帮助。解释一下您的代码是如何不同的，这将是一个更好的答案。是的，读者必须逐行比较您的代码与原始代码，以查看您更改了什么。就个人而言，我不介意逐行检查代码以找出差异，因为这有助于我的理解，但是，我可以看到一些人不想这样做。。非常感谢大家的帮助。如果这解决了你的问题，如果你能接受我的回答，我将不胜感激。谢谢
