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

Why don't you just use subprocess.call on tail itself?

subproces.call(['tail', '-f', filename])

Edit: Fixed to eliminate extra shell process.

Edit2: Fixed to eliminate deprecated os.popen and thus the need to interpolate parameters, escape espaces and other stuff, and then run a shell process.
