python编写一个答题系统，其中选项和题目都存储在mysql名叫shuju的数据库中的questions表中，题目名称叫做question，第一个选项名option_a,第二个option_b，第三个option_c，第四个option_d，存储正确答案的字段名是answer，他存储的是正确选项的字段名，我一共存储了三道题 要求题目在最上面，四个选项在中间， 四个选项的下面正中间放在一行的是下一题和结果按钮，首先答题过程中，选中答案，单击下一题后，出现本题是否答对的弹窗然后 就在当前窗口将mysql数据库中下一个题的题目和选项更新替换到当前窗口的题目和选项中，最后一个题目更新替换到当前窗口的时候，再点击下一题就弹出一个窗口提示是否大队并且提示这是最后一，答对一题获得10分，我点击结果按钮就弹出窗口显示你获得的分数

好的，我来解答你的问题。对于你的要求，我可以给出以下的答案：

首先，你需要安装mysql-connector-python这个库，通过以下命令安装：

pip install mysql-connector-python

接着，你需要编写一个Python程序，实现题目和选项的显示、答案的判断和分数的计算。具体的实现步骤如下：

1. 连接mysql数据库

import mysql.connector

mydb = mysql.connector.connect(
  host="localhost",
  user="yourusername",
  password="yourpassword",
  database="shuju"
)

mycursor = mydb.cursor()

2. 查询题目和选项

mycursor.execute("SELECT question, option_a, option_b, option_c, option_d, answer FROM questions")
result = mycursor.fetchall() # 获取所有题目和选项

3. 显示题目和选项

import tkinter

def show_question():
    question_label.config(text=result[current_question][0])
    option_a.config(text=result[current_question][1])
    option_b.config(text=result[current_question][2])
    option_c.config(text=result[current_question][3])
    option_d.config(text=result[current_question][4])

4. 判断答案是否正确

def check_answer(answer):
    if result[current_question][5] == answer:
        return True
    else:
        return False

5. 计算分数

score = 0

def add_score():
    global score
    score += 10
    score_label.config(text="Score: {}".format(score))

6. 显示结果

def show_result():
    result_window = tkinter.Toplevel()
    result_text = "Your score is {}".format(score)
    result_label = tkinter.Label(result_window, text=result_text)
    result_label.pack()

7. 完整代码

import mysql.connector
import tkinter

mydb = mysql.connector.connect(
  host="localhost",
  user="yourusername",
  password="yourpassword",
  database="shuju"
)

mycursor = mydb.cursor()

mycursor.execute("SELECT question, option_a, option_b, option_c, option_d, answer FROM questions")
result = mycursor.fetchall()

current_question = 0
score = 0

def show_question():
    question_label.config(text=result[current_question][0])
    option_a.config(text=result[current_question][1])
    option_b.config(text=result[current_question][2])
    option_c.config(text=result[current_question][3])
    option_d.config(text=result[current_question][4])

def check_answer(answer):
    if result[current_question][5] == answer:
        return True
    else:
        return False

def add_score():
    global score
    score += 10
    score_label.config(text="Score: {}".format(score))
    
def show_result():
    result_window = tkinter.Toplevel()
    result_text = "Your score is {}".format(score)
    result_label = tkinter.Label(result_window, text=result_text)
    result_label.pack()

def next_question():
    global current_question
    if current_question == len(result)-1: # 最后一题
        if check_answer(answer.get()): # 答对
            add_score()
        show_result()
        return
    if check_answer(answer.get()): # 答对
        add_score()
    current_question += 1
    show_question()

root = tkinter.Tk()

question_label = tkinter.Label(root, text="")
question_label.pack()

answer = tkinter.StringVar()

option_a = tkinter.Radiobutton(root, text="", variable=answer, value="option_a")
option_b = tkinter.Radiobutton(root, text="", variable=answer, value="option_b")
option_c = tkinter.Radiobutton(root, text="", variable=answer, value="option_c")
option_d = tkinter.Radiobutton(root, text="", variable=answer, value="option_d")

option_a.pack()
option_b.pack()
option_c.pack()
option_d.pack()

next_button = tkinter.Button(root, text="Next", command=next_question)
next_button.pack()

score_label = tkinter.Label(root, text="Score: 0")
score_label.pack()

result_button = tkinter.Button(root, text="Result", command=show_result)
result_button.pack()

show_question()

root.mainloop()

希望这个答案能够帮到你！
