Overview

Enlighten Progress Bar is a console progress bar module for Python. (Yes, another one.)

The main advantage of Enlighten is it allows writing to stdout and stderr without any redirection.

Installation

PIP

$ pip install enlighten

EL6 and EL7 (RHEL/CentOS/Scientific)

(EPEL repositories must be configured)

$ yum install python-enlighten

Fedora

$ dnf install python2-enlighten
$ dnf install python3-enlighten

Examples

Basic

For a basic status bar, invoke the Counter class directly.

import time
import enlighten

pbar = enlighten.Counter(total=100, desc='Basic', unit='ticks')
for num in range(100):
    time.sleep(0.1)  # Simulate work
    pbar.update()

Advanced

To maintain multiple progress bars simultaneously or write to the console, a manager is required.

Advanced output will only work when the output stream, sys.stdout by default, is attached to a TTY. get_manager can be used to get a manager instance. It will return a disabled Manager instance if the stream is not attached to a TTY and an enabled instance if it is.

import time
import enlighten

manager = enlighten.get_manager()
ticks = manager.counter(total=100, desc='Ticks', unit='ticks')
tocks = manager.counter(total=20, desc='Tocks', unit='tocks')

for num in range(100):
    time.sleep(0.1)  # Simulate work
    print(num)
    ticks.update()
    if not num % 5:
        tocks.update()

manager.stop()

Counters

The Counter class has two output formats, progress bar and counter.

The progress bar format is used when a total is not None and the count is less than the total. If neither of these conditions are met, the counter format is used:

import time
import enlighten

counter = enlighten.Counter(desc='Basic', unit='ticks')
for num in range(100):
    time.sleep(0.1)  # Simulate work
    counter.update()

Additional Examples

Customization

Enlighten is highly configurable. For information on modifying the output, see the Series and Format sections of the Counter documentation.
