我有一个测验代码，但只出现第一个问题。我可以回答第一个问题，分数会相应调整，但下一个问题永远不会出现。我已经尝试过研究通过元组循环并且使用我的代码但是无济于事。我是一个Python新手，并希望得到一些帮助。我花了好几个小时相信我。
number答案 0 :(得分：0)
这应该有效。我在函数submit_button_clicked()中添加了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()
语句，因此如果问题是最后一个，它仍会更新分数。如果你仔细阅读代码，你应该看到我改变了什么。如果你不理解，请不要。祝你有美好的一天！
