tail -f in python with no time.sleep

Question

I need to emulate \"tail -f\" in python, but I don\'t want to use time.sleep in the reading loop. I want something more elegant like some kind of blocking read, or select.se

Answer 1

IMO you should use sleep, it works on all platform and code will be simple

Otherwise you can use platform specific APIs which can tell you when file change e.g. on window use FindFirstChangeNotification on folder and watch for FILE_NOTIFY_CHANGE_LAST_WRITE events

On linux i think you can use i-notify

On Mac OSX use FSEvents
