用Python帮我写一个多功能时钟

好的，我可以帮你编写一个多功能时钟。你需要安装 Python 的 datetime 模块和 tkinter 模块。

下面是代码：

import datetime
import tkinter as tk

class Clock:
    def __init__(self, master):
        self.master = master
        self.master.title("多功能时钟")
        
        self.frame1 = tk.Frame(master)
        self.frame1.pack()
        
        self.label_time = tk.Label(self.frame1, font=("Helvetica", 48), fg="green")
        self.label_time.pack()
        self.update_time()
        
        self.frame2 = tk.Frame(master)
        self.frame2.pack()
        
        self.button_date = tk.Button(self.frame2, text="当前日期", command=self.show_date)
        self.button_date.pack(side="left")
        
        self.button_alarm = tk.Button(self.frame2, text="设置闹钟", command=self.set_alarm)
        self.button_alarm.pack(side="left")
        
        self.button_stopwatch = tk.Button(self.frame2, text="秒表", command=self.stopwatch)
        self.button_stopwatch.pack(side="left")
        
        self.button_timer = tk.Button(self.frame2, text="计时器", command=self.timer)
        self.button_timer.pack(side="left")
        
        self.alarm_time = None
        self.stopwatch_time = 0
        self.timer_time = 0
        self.timer_running = False
        
    def update_time(self):
        now = datetime.datetime.now().strftime("%H:%M:%S")
        self.label_time.config(text=now)
        self.master.after(1000, self.update_time)
        
    def show_date(self):
        now = datetime.datetime.now().strftime("%Y-%m-%d")
        tk.messagebox.showinfo("当前日期", now)
        
    def set_alarm(self):
        alarm = tk.simpledialog.askstring("设置闹钟", "请输入闹钟时间(HH:MM:SS)")
        if alarm:
            try:
                self.alarm_time = datetime.datetime.strptime(alarm, "%H:%M:%S").time()
                tk.messagebox.showinfo("设置闹钟", "闹钟已设置为：" + alarm)
            except ValueError:
                tk.messagebox.showerror("设置闹钟", "无效的时间格式! 请使用 HH:MM:SS")
                
    def check_alarm(self):
        if self.alarm_time and self.alarm_time <= datetime.datetime.now().time():
            tk.messagebox.showinfo("闹钟", "时间到了！")
            self.alarm_time = None
            
    def stopwatch(self):
        self.stopwatch_time = 0
        self.button_stopwatch.config(text="0.00")
        self.button_stopwatch.config(state="disabled")
        self.button_timer.config(state="disabled")
        self.master.after(10, self.update_stopwatch)
        
    def update_stopwatch(self):
        self.stopwatch_time += 0.01
        self.button_stopwatch.config(text="{:.2f}".format(self.stopwatch_time))
        if self.button_stopwatch["state"] == "normal":
            return
        self.master.after(10, self.update_stopwatch)
        
    def timer(self):
        if not self.timer_running:
            self.timer_time = tk.simpledialog.askinteger("计时器", "请输入计时器时间(秒)")
            if self.timer_time:
                self.timer_running = True
                self.button_timer.config(text=str(self.timer_time))
                self.button_stopwatch.config(state="disabled")
                self.button_date.config(state="disabled")
                self.button_alarm.config(state="disabled")
                self.run_timer()
        else:
            self.timer_running = False
            self.button_timer.config(text="计时器")
            self.button_stopwatch.config(state="normal")
            self.button_date.config(state="normal")
            self.button_alarm.config(state="normal")
            
    def run_timer(self):
        self.timer_time -= 1
        self.button_timer.config(text=str(self.timer_time))
        if self.timer_time == 0:
            tk.messagebox.showinfo("计时器", "时间到了！")
            self.timer_running = False
            self.button_timer.config(text="计时器")
            self.button_stopwatch.config(state="normal")
            self.button_date.config(state="normal")
            self.button_alarm.config(state="normal")
        elif self.timer_running:
            self.master.after(1000, self.run_timer)
          
root = tk.Tk()
clock = Clock(root)
root.mainloop()

这个时钟可以显示当前时间，还可以进行以下操作：

- 显示当前日期
- 设置闹钟
- 秒表
- 计时器

你可以通过点击相应的按钮来执行这些操作。希望这个多功能时钟对你有所帮助！
