This stops the loop after 30s but the program uses about 12% cpu. What
would be a more efficient way to do this? (p.s. i'm on python 2.7.3)
import time
time.sleep(30)
print "Done sleeping"
By the way, if you decide to use a while loop, don't test for time == s
exactly. If the timer misses your target by even a billionth of a second,
the loop will never end. Better is:
stop = time.time() + 30
while time.time() < stop:
pass
print "Done"
but don't do this either, use time.sleep.
