在特定的一天每小时运行一个脚本

Question

I want to use the Advanced Python Scheduler ( https://apscheduler.readthedocs.io/en/stable/ ) in order to scrape popular times from Google every hour (40 grocery stores in list markets, from 6:00 to 18:00) on a specific day.

My code works if I start it manually every hour, but I don't know how to write correct code in order to start the AP Scheduler. It was running for quite some time, but the resulting data frame was empty.

I was looking into the manual and other questions, but I couldn't figure out how to write the code.

from apscheduler.schedulers.blocking import BlockingScheduler

def job():
    for market in markets:
        data = livepopulartimes.get_populartimes_by_address(market)
        current_popularity_ = pd.DataFrame([[date.today().strftime("%Y-%m-%d"), 
                           date.today().strftime("%A"),
                           datetime.now().strftime("%H:%M:%S"),
                           pd.DataFrame.from_dict(data, orient='index').loc['current_popularity'].values[0]
                          ]],
             columns=['date','day','time','value'])
        current_popularity_['market'] = market
        current_popularity = current_popularity.append(current_popularity_)

sched = BlockingScheduler()

sched.add_job(
    job, 
    trigger='cron',
    hour='06-18',
    start_date = '2021-02-04',
    end_date = '2021-02-04'
)

sched.start()

Answer 1

So I corrected the dates in my code and tried to run it again. But again, it didn't work. The resulting data frame was empty. The code works if I start it manually (data frame is not empty). So if anyone has an idea what is wrong with the code for the scheduler, please let me know.
