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.

The code for this animation can be found in demo.py in examples.

https://python-enlighten.readthedocs.io

$ pip install enlighten

(EPEL repositories must be configured)

$ yum install python-enlighten

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

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()

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()

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()

• basic - Basic progress bar
• context manager - Managers and counters as context managers
• floats - Support totals and counts that are floats
• multicolored - Multicolored progress bars
• multiple with logging - Nested progress bars and logging
• FTP downloader - Show progress downloading files from FTP

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