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. :

from progress.bar import Bar

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

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:

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

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 4 predefined spinners:

• Spinner
• PieSpinner
• MoonSpinner
• LineSpinner

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