编写Python定时弹窗通知脚本及多提醒仅首个生效问题求助

故障根因 #

你的alert函数内部嵌入了while True死循环，程序执行到第一个alert调用时会永久卡在此函数的循环逻辑中，永远无法执行后续的alert调用，因此只有第一条提醒规则会生效。

修正方案 #

将所有提醒规则整理为统一列表，使用单个全局循环轮询所有规则即可，修正后代码如下：

import time
from win10toast import ToastNotifier

notify = ToastNotifier()
IconPath = "C:\\Users\\Hash\\Downloads\\Pill0.ico"

# 统一维护所有提醒规则：格式为(提醒小时, 提醒分钟, 提醒内容)
alert_rules = [
    (21, 30, ">>>> E P I C I P R I N  5ML <<<<"),
    (17, 48, ">>>> seccE P I C I P R I N  5ML <<<<"),
    (9, 15, ">>>> P A T A N O L <<<<"),
    (21, 15, ">>>> P A T A N O L <<<<"),
    (9, 32, ">>>> E P I C I P R I N  5ML <<<<"),
    (15, 32, ">>>> E P I C I P R I N  5ML <<<<"),
    (21, 32, ">>>> E P I C I P R I N  5ML <<<<"),
    (3, 32, ">>>> E P I C I P R I N  5ML <<<<"),
    (9, 50, ">>>> E P I F E N A C <<<<"),
    (17, 50, ">>>> E P I F E N A C <<<<"),
    (1, 50, ">>>> E P I F E N A C <<<<"),
    (22, 00, ">>>> E P I C I P R I N  5G <<<<")
]

def run_alert():
    last_trigger_minute = -1
    while True:
        current_ts = time.time()
        current_hour = int(current_ts // 3600 % 24)
        current_minute = int(current_ts // 60 % 60)
        # 同一分钟只触发一次，避免重复弹窗
        if current_minute == last_trigger_minute:
            time.sleep(30)
            continue
        # 遍历所有提醒规则
        for hour, minute, msg in alert_rules:
            if current_hour == hour and current_minute == minute:
                notify.show_toast("Drop Time!", msg, duration=120, icon_path=IconPath)
        last_trigger_minute = current_minute
        time.sleep(30)

if __name__ == "__main__":
    run_alert()

优化说明 #

• 所有提醒规则统一管理，新增/修改规则只需修改alert_rules列表即可
• 单循环轮询所有规则，解决了原代码死循环阻塞后续执行的问题
• 增加了分钟去重逻辑和休眠逻辑，既避免了同一分钟重复触发同一条提醒，也降低了CPU空转占用
