Introduction

NOTE: This version has been completely rewritten and might not be 100% compatible with the old version. If you encounter any problems while using it please let me know: https://github.com/WoLpH/python-progressbar/issues

A text progress bar is typically used to display the progress of a long running operation, providing a visual cue that processing is underway.

The ProgressBar class manages the current progress, and the format of the line is given by a number of widgets. A widget is an object that may display differently depending on the state of the progress bar. There are many types of widgets:

• Timer
• ETA
• AdaptiveETA
• FileTransferSpeed
• AdaptiveTransferSpeed
• AnimatedMarker
• Counter
• Percentage
• FormatLabel
• SimpleProgress
• Bar
• ReverseBar
• BouncingBar
• RotatingMarker
• DynamicMessage

The progressbar module is very easy to use, yet very powerful. It will also automatically enable features like auto-resizing when the system supports it.

Usage

There are many ways to use Python Progressbar, you can see a few basic examples here but there are many more in the examples file.

Wrapping an iterable

import time
import progressbar

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

Context wrapper

import time
import progressbar

with progressbar.ProgressBar(max_value=10) as bar:
    for i in range(10):
        time.sleep(0.1)
        bar.update(i)

Combining progressbars with print output

import time
import progressbar

bar = progressbar.ProgressBar(redirect_stdout=True)
for i in range(100):
    print 'Some text', i
    time.sleep(0.1)
    bar.update(i)

Progressbar with unknown length

import time
import progressbar

bar = progressbar.ProgressBar(max_value=progressbar.UnknownLength)
for i in range(20):
    time.sleep(0.1)
    bar.update(i)

Bar with custom widgets

import time
import progressbar

bar = progressbar.ProgressBar(widgets=[
    ' [', progressbar.Timer(), '] ',
    progressbar.Bar(),
    ' (', progressbar.ETA(), ') ',
])
for i in bar(range(20)):
    time.sleep(0.1)
