(python) Telegram bot- how to send messages periodically?

Question

I have a dilemma regarding my telegram bot. Let's say I have to create a function that will ask, every user connected to the bot, one time per week/month, a question:

def check_the_week(bot, update):
reply_keyboard = [['YES', 'NO']]
bot.send_message(
    chat_id=update.message.chat_id,
    text=report,

    reply_markup=ReplyKeyboardMarkup(reply_keyboard, one_time_keyboard=True))  # sends the total nr of hours
update.reply_text("Did you report all you working hour on freshdesk for this week?",
                  ReplyKeyboardMarkup(reply_keyboard, one_time_keyboard=True))

if update.message.text == "YES":
    update.message.reply_text(text="Are you sure?",
                              reply_markup=ReplyKeyboardMarkup(reply_keyboard, one_time_keyboard=True))

    # Asks confirmation
    if update.message.text == "YES":
        update.message.reply_text(text="Thank you for reporting your working hours in time!")

    elif update.message.text == "NO":
        update.message.reply_text(text="Please, check you time reports and add missing")

elif update.message.text == "NO":
    update.message.reply_text(text="Please, check you time reports and add missing")

I want this function to be triggered every week. I was thinking about using JobQueue. The problem is that in this case the function should have two parameters- bot AND job_queue, but no update:

def callback_30(bot, job):
    bot.send_message(chat_id='@examplechannel',
    text='A single message with 30s delay')

j.run_once(callback_30, 30)

How can I create a Job Scheduler (or any other solution) in telegram bot to be trigger my function once a week? p.s. No "while True"+time.sleep() solutions please. The loop just stuck forever, I tried it.

You need to use the context parameter when defining the job in your function. Look at this example:

   from telegram.ext import Updater, CommandHandler, MessageHandler,    Filters, InlineQueryHandler


def sayhi(bot, job):
    job.context.message.reply_text("hi")

def time(bot, update,job_queue):
    job = job_queue.run_repeating(sayhi, 5, context=update)

def main():
    updater = Updater("BOT TOKEN")
    dp = updater.dispatcher
    dp.add_handler(MessageHandler(Filters.text , time,pass_job_queue=True))


    updater.start_polling()
    updater.idle()

if __name__ == '__main__':
    main()

Now in your call back function wherever you need update. type job.context instead.
