Easy to use progress bars

Easy progress reporting for Python

Bars

There are 7 progress bars to choose from:

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

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

from progress.bar import Bar

bar = Bar('Processing', max=20)
for i in range(20):
    # Do some work
    bar.next()
bar.finish()

or use any bar of this class as a context manager:

from progress.bar import Bar

with Bar('Processing', max=20) as bar:
    for i in range(20):
        # Do some work
        bar.next()

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:

for i in Bar('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:

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

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

class SlowBar(Bar):
    suffix = '%(remaining_hours)d hours remaining'
    @property
    def remaining_hours(self):
        return self.eta // 3600

Spinners

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

from progress.spinner import Spinner

spinner = Spinner('Loading ')
while state != 'FINISHED':
    # Do some work
    spinner.next()

There are 5 predefined spinners:

• Spinner
• PieSpinner
• MoonSpinner
• LineSpinner
• PixelSpinner
