For progress reporting, I often use the module below (eta.py), which also gives
a projected time of completion:
import datetime, time, sys
etastart = 0
def eta(done, total, s, reportinterval=100, datetimeformat="%d %b %H:%M:%S"):
global etastart
if done == 0:
etastart = datetime.datetime.now()
if not done % reportinterval:
noww = datetime.datetime.now()
prtnow = noww.strftime(datetimeformat)
if done:
if not isinstance(etastart, datetime.datetime): raise
RuntimeError("You should call eta() at least once with done=0")
elapsed = noww - etastart
secsperitem = float(elapsed.seconds) / done
totalsecs = secsperitem * total
eta = etastart + datetime.timedelta(0, totalsecs)
prteta = eta.strftime(datetimeformat)
msg = "now %s, eta %s (%d/%d) %s" % (prtnow, prteta, done, total, s)
else:
msg = "now %s (%d/%d) %s" % (prtnow, done, total, s)
sys.stderr.write(msg + "\n")
if __name__ == "__main__":
for i in range(10):
eta(i, 10, "idling for ten seconds", 1, "%H:%M:%S")
time.sleep(1)
