I have a Python script running that checks to see if slots have opened up for a
class I want to take next semester, and then it emails me.
Problem
I can’t have my laptop in all the time. Is there any resource available to let me house my script and just let it run on some server.
Or better yet, is there anyway to run a script like this on an Android phone.
If you are scraping a web page, you could use scraperwiki. It allows you to run scraper code on their server for free. (lxml is importable there too!) You can set how frequently you want the script to run.
