Easy progress reporting for Python

Bars

There are 6 progress bars to choose from:

• Bar
• ChargingBar
• FillingSquaresBar
• FillingCirclesBar
• IncrementalBar
• ShadyBar

To use them, just call next to advance and finish to finish:

fromprogress.barimportBarbar=Bar('Processing', max=20)
foriinrange(20):
# Do some workbar.next()
bar.finish()

The result will be a bar like the following:

Processing |############# | 42/100

To simplify the common case where the work is done in an iterator, you can use the iter method:

foriinBar('Processing').iter(it):
# Do some work

Progress bars are very customizable, you can change their width, their fill character, their suffix and more:

bar=Bar('Loading', fill='@', suffix='%(percent)d%%')

This will produce a bar like the following:

Loading |@@@@@@@@@@@@@ | 42%

You can use a number of template arguments in message and suffix:

Name	Value
index	current value
max	maximum value
remaining	max - index
progress	index / max
percent	progress * 100
avg	simple moving average time per item (in seconds)
elapsed	elapsed time in seconds
elapsed_td	elapsed as a timedelta (useful for printing as a string)
eta	avg * remaining
eta_td	eta as a timedelta (useful for printing as a string)

Instead of passing all configuration options on instatiation, you can create your custom subclass:

classFancyBar(Bar):
message='Loading'fill='*'suffix='%(percent).1f%% - %(eta)ds'

You can also override any of the arguments or create your own:

classSlowBar(Bar):
suffix='%(remaining_hours)d hours remaining'@propertydefremaining_hours(self):
returnself.eta//3600

Spinners

For actions with an unknown number of steps you can use a spinner:

fromprogress.spinnerimportSpinnerspinner=Spinner('Loading ')
whilestate!='FINISHED':
# Do some workspinner.next()

There are 4 predefined spinners:

• Spinner
• PieSpinner
• MoonSpinner
• LineSpinner

Other

There are a number of other classes available too, please check the source or subclass one of them to create your own.
