帮我写一个小猿口算PK的代码

小猿口算PK的代码通常涉及到简单的用户界面交互，下面是一个简单的Python示例，使用tkinter库模拟两个玩家轮流输入数字进行加减运算：

import tkinter as tk

def calculate(num1, num2, operator):
    if operator == '+':
        result = num1 + num2
    elif operator == '-':
        result = num1 - num2
    else:
        return "错误的操作符"

    return result

class MathGame:
    def __init__(self, root):
        self.root = root
        self.player1_score = 0
        self.player2_score = 0
        
        # 创建操作按钮和文本框
        self.btn1 = tk.Button(root, text="玩家1+")
        self.btn1.bind("<Button-1>", lambda event: self.check_answer("player1", "+"))
        self.btn2 = tk.Button(root, text="玩家1-")
        self.btn2.bind("<Button-1>", lambda event: self.check_answer("player1", "-"))
        self.btn1.grid(row=0, column=0)
        self.btn2.grid(row=0, column=1)

        self.btn3 = tk.Button(root, text="玩家2+")
        self.btn3.bind("<Button-1>", lambda event: self.check_answer("player2", "+"))
        self.btn4 = tk.Button(root, text="玩家2-")
        self.btn4.bind("<Button-1>", lambda event: self.check_answer("player2", "-"))
        self.btn3.grid(row=1, column=0)
        self.btn4.grid(row=1, column=1)
        
        self.score_label = tk.Label(root, text="")
        self.score_label.grid(row=2, columnspan=2)
        
    def check_answer(self, player, operator):
        try:
            num1 = int(self.entry.get())
            num2 = int(self.entry.get())
            result = calculate(num1, num2, operator)
            print(f"{player} 的结果: {result}")
            
            # 更新得分并清空输入框
            if result % 2 == 0:
                self.update_score(player, 1)
            else:
                self.update_score(player, -1)
            self.entry.delete(0, tk.END)
        except ValueError:
            print("请输入数字!")

    def update_score(self, player, score):
        self.player1_score += score if player == 'player1' else -score
        self.player2_score += score if player == 'player2' else -score
        self.score_label.config(text=f"玩家1: {self.player1_score}, 玩家2: {self.player2_score}")

# 主函数
if __name__ == "__main__":
    root = tk.Tk()
    app = MathGame(root)
    root.mainloop()
