python随机加减法图形界面

可以使用 Python 的 tkinter 库来创建图形界面，并结合 random 模块来进行随机加减法的操作。下面是一个简单的示例代码：

import random
import tkinter as tk

class MathGame:
    def __init__(self, master):
        self.master = master
        master.title("随机加减法")
        
        self.num1 = random.randint(1, 10)
        self.num2 = random.randint(1, 10)
        self.operator = random.choice(['+', '-'])
        
        self.question = tk.Label(master, text=f"{self.num1} {self.operator} {self.num2}")
        self.question.pack()
        
        self.answer_entry = tk.Entry(master)
        self.answer_entry.pack()
        
        self.check_button = tk.Button(master, text="检查答案", command=self.check_answer)
        self.check_button.pack()

        self.result_label = tk.Label(master, text="")
        self.result_label.pack()

    def check_answer(self):
        try:
            user_answer = int(self.answer_entry.get())
        except ValueError:
            self.result_label.config(text="请输入一个整数")
            return
        
        if self.operator == '+':
            correct_answer = self.num1 + self.num2
        else:
            correct_answer = self.num1 - self.num2
        
        if user_answer == correct_answer:
            self.result_label.config(text="回答正确！")
        else:
            self.result_label.config(text="回答错误。正确答案是：" + str(correct_answer))
        
        self.num1 = random.randint(1, 10)
        self.num2 = random.randint(1, 10)
        self.operator = random.choice(['+', '-'])
        self.question.config(text=f"{self.num1} {self.operator} {self.num2}")
        self.answer_entry.delete(0, tk.END)

root = tk.Tk()
math_game = MathGame(root)
root.mainloop()

运行代码后，会弹出一个窗口，每次点击“检查答案”按钮时，会随机生成一个加减法问题，用户输入答案后，程序会告诉用户答案是否正确。
