a function to suspend execution, sleep() uses cpu

[elnaz1010]

I am using my host to run a python script as a program.
My script is checking a website every 15 minutes and get the news but the problem is sleep() uses cpu, and my host won't accept this.

I want a function or a method to block the execution until 15min later.

I tried to use semaphores, but it require some library which my host won't install them for me.

[woooee]

sleep() of course has to check the time periodically to see if it should wake up. If you can, submit the program every 15 minutes to the host, run and exit.

Thanks for your reply, I appreciate it, but the problem is 15 minutes is not a static running time.
In some situation, 15min will reduce to 30 second, and thats when I can submit it.

Another problem is my script is going to be a crawler, it should be automatic. If I submit it every 15min, it require a request. As you know this method is not making a crawler.

Anyway, thanks :)
