How to run a Python script online every N minutes?

Question

To work a bit on my Python, I decided to try to code a simple script for my private use which monitors sites with offers and sends you an email whenever a new offer which you are interested in pops out. I guess I could handle the coding part (extracting the newest one from HTML and such) but I've never really run online any script which requires being fired every N minutes or so. What kind of hosting/server do I need to make my script run independently of my computer and refresh every, say, 5 minutes sending me an email when there's an update?

If you have shell access, you an use crontab to schedule a recurring job.

Otherwise you can use a service like SetCronJob or EasyCron or similar to invoke a script regularly.

Some hosters also provide similar functionalities in their administration interface...
