[Tutor] Python Timer

[Dick Moores]

Joe, if you rely on time.sleep() in counting seconds, check out the 
inaccuracy that builds up:

=======================
from time import sleep, time

def ansi(str):
         return chr(27)+'['+str
x = 0
startTime = time()
while 1:
         x=x+1
         print x,
         sleep(1)
         currentTime = time()
         print ansi('0E')+ansi('K'),
         print "%.3f" % (currentTime - startTime),
=================================
