### 导入包 ###

import tkinter as tk
    import time

### 初始化 ###

            master.title("Countdown Timer")

            self.minutes = tk.StringVar(value=str(minutes))  # 设置默认值
            self.seconds = tk.StringVar(value=str(seconds))  # 设置默认值
    
            # 创建分钟和秒钟输入框
            tk.Label(master, text="分:").grid(row=0, column=0)

            self.start_button = tk.Button(master, text="开始", command=self.start_timer)
            self.start_button.grid(row=3, column=0, pady=10)
