多个计时器一次

Question

编辑：我现在得到一个运行时错误：当第二个计时器达到 0 并调用 Note() 函数时，'主线程不在主循环中'

from datetime import datetime
from threading import Timer
from tkinter import messagebox
import json


def Note():
    z = messagebox.showinfo("Note", note)

class Timers:
    def __init__(self,a,b,c,d,e):
        self.a = month
        self.b = day
        self.c = hour
        self.d = minute
        self.e = note
        x = datetime.today()
        y = x.replace(month=month, day=day, hour=hour, minute=minute, second=0, microsecond=0)
        delta_t = y - x
        secs = delta_t.seconds


        T = Timer(secs, Note)
        T.start()

Answer 1

您可能想使用 json 来存储数据对象列表

def save_some_object(a,b,c):
    with open("some_file.txt","wb") as f:
         json.dump({'a':a,'b':b},f)

在您的情况下，您要保存的对象是日期时间元数据的 LIST

alarms_list = [{'hour':5,'minute':5,'second':0,'day':1,'month':1,'year':2019}, {'hour':6,'minute':5,'second':0,'day':1,'month':1,'year':2021}]

然后您可以将它们保存到您的文件中

with open("some_file.txt","wb") as f:
     json.dump(alarms_list,f)

您也可以使用 json 加载警报列表

with open("some_file.txt","rb") as f:
     my_alarm_data_list = json.load(f)
