python设定闹钟提醒

import time
import datetime

# 设置提醒时间（24小时制）
study_time = "8:00:00"
eat_time = "12:00:00"
sleep_time = "23:00:00"

while True:
    # 获取当前时间
    now = datetime.datetime.now().strftime("%H:%M:%S")
    
    # 如果当前时间与提醒时间相同，则提醒
    if now == study_time:
        print("该上课了！")
    elif now == eat_time:
        print("该吃饭了！")
    elif now == sleep_time:
        print("该睡觉了！")
    else:
        print("无事可做")
        
        # 延迟1分钟，避免重复提醒
        time.sleep(60)
