电报机器人 api 如何安排通知？

Question

I've made a bot that gets today football matches and if the user wants he can get a reminder 10 min before a selected match.

while current_time != new_hour:
        now = datetime.now()
        current_time = now.strftime("%H:%M")
#return notification
    text_caps = "Your match starts in 10 minutes"
    context.bot.send_message(chat_id=update.effective_chat.id, text=text_caps)

Obviously while the loop runs i can not use another command. I am new to programming how could i implement this so i still get the notification but while that runs i can use other commands?

Thank you!

Answer 1

Try to use an aiogram and you can make scheduled tasks with aiocron (store users who wants to get notification in database or in global dict)

Answer 2

You can schedule a job.
Let's say you have a CommandHandler("watch_match", watch_match) that listens for a /watch_match conmmand and 10 minutes later a message is supposed to arrive

def watch_match(update: Update, context: CallbackContext):
    chat_id = update.effective_chat.id
    ten_minutes = 60 * 10 # 10 minutes in seconds  
    context.job_queue.run_once(callback=send_match_info, when=ten_minutes, context=chat_id) 
    # Whatever you pass here as context is available in the job.context variable of the callback

def send_match_info(context: CallbackContext):
    chat_id = context.job.context
    context.bot.send_message(chat_id=chat_id, text="Yay")

A more detailed example in the official repository
And in the official documentation you can see the run_once function
