Web scraping for weather warning notifications.

Please let me know the alert on Twitter.

Motivation

I did it

I'm a high school student. The school will be closed due to an alarm. The pious time to check the alarms one by one on that poorly responsive NHK data broadcast is too exciting, so I would like you to be notified automatically on Twitter. Yes.

problem

Somehow, there is no alarm API at all. I found it when I was looking for it, but apparently it seems that I'm using a bubbly protocol called "Habusabu Pab Bab".

...

Web scraping !!

This is it !!

environment

• Python3
• urllib
• BeatifulSoup4 --twitter (Python library)

It feels like it.

    main()

• I'm sorry I didn't cut it. .. .. The URL is the Yahoo weather alert page.

result

I can do it.

Good vibes.

Link this with Raspberry Pi to lock the house when an alarm is issued www
