Like a stopwatch, but it also gives you an ETA.
Example usage:
# construction immediately starts timer
eta_watch = etawatch(5)
for i in range(number_of_laps):
# do some work
time.sleep(random.randint(1, 3))
eta, lap = eta_watch()
print(f'Lap: {i+1} | Time: {lap:.2f} sec | ETA: {eta:.2f} min')Another example:
for i, (eta, lap) in enumerate(etawatch(5)):
# do some work
time.sleep(random.randint(1, 3))
print(f'Lap: {i+1} | Time: {lap:.2f} sec | ETA: {eta:.2f} min')It can optionally predict ETA by only the last n number of runs.
# will only calculate ETAs based on last 3 lap times
eta = etawatch(10, 3)
