python tkinter "in“操作符不起作用

Question

我的问题是，只有当你单独输入答案时，程序才会声明答案是正确的，但我想让你实际上可以在entry小工具中放置一个短语，如果答案在该短语中，它会说正确，我在没有tkinter的情况下完成了这项工作，但我不能让它在tkinter中工作。这是我的代码，可以帮助我吗，谢谢。

代码

import tkinter as tk
from time import sleep

win = tk.Tk()

win.title("Learning game")

class Question:
    def __init__(self,prompt,answer):
        self.answer = answer
        self.prompt = prompt

score = 0



def ask():
    global questions
    global useranwser
    global score
    if questions:
            #Check both the possible answers
        if useranwser.get() in questions[0].answer:
            print("Correct")
            score += 1
        else:
            print("Incorrect")
        questions.pop(0)
        if questions:
            s.set(questions[0].prompt) 
        else:
            print('Done')
            print("Your score is : ",score)
            quit() #optional
        useranwser.set('')


question_prompts = [
    "When did Tunisia gain independence? \n 1956 , 1984  , 1965 \n", "What is the captial of tunis ? \n Tunis, Gafsa, Nabuel \n",
    "Who won 2018 football world cup ? \n Italy, France, England \n","how long is the eiffel tower ?\n 324m, 354m, 412m \n",
    "What is the heaviest metal \n Iron, Copper, Uraniam \n "
]

questions = [
    Question(question_prompts[4], "uraniam"),
    Question(question_prompts[0], "1956"),
    Question(question_prompts[1], "tunis"),
    Question(question_prompts[2], "france"),
    Question(question_prompts[3], "324m")
]

s = tk.StringVar()
useranwser = tk.StringVar() 
q = tk.Label(win,textvariable = s)
q.grid(row = 0, column = 0)
u_answer = tk.Entry(win, textvariable = useranwser)
u_answer.grid(row = 1, column = 0)
b = tk.Button(win, text ="Submit", command = ask)
b.grid(row = 2, column =0 )
s.set(questions[0].prompt)#Set the initial question 

 

win.mainloop()

我不得不将这条if语句从下面的语句中翻转过来：

if useranwser.get() in questions[0].answer:
            print("Correct")
            score += 1

要这样做：

if questions[0].answer in useranwser.get():
            print("Correct")
            score += 1
