Description

Progressbar as wrapped iterable show to high ETA if iterations take less than _MINIMUM_UPDATE_INTERVAL.

The example code from the documentation jumps from

38% (38 of 100) |######### | Elapsed Time: 0:00:01 ETA: 0:00:03

to

100% (100 of 100) |#######################| Elapsed Time: 0:00:02 Time: 0:00:02

The reason is that the wrapper around the iterable calls self.update(self.value + 1) but self.value is not updated if the time from last update is less than _MINIMUM_UPDATE_INTERVAL.

Code

Just added print statement to example code from documentation to show the mismatch between internal value and actual iteration.

import time
import progressbar

bar = progressbar.ProgressBar()
for i in bar(range(100)):
    print(i, bar.value)
    time.sleep(0.02)
