Pygress

by Elvin Yung

Simple command-line progress bars in Python

Install

It's on PyPi! Install it using pip install pygress.

Right now I've only tested this with Python 3.3.4.

Quickstart

from pygress import ProgressBar

progress_bar = ProgressBar()
task = SomethingThatTakesTime()
while True:
    progress_bar.set_progress(task.progress)
    progress_bar.render()
    if task.progress >= 1.0:
        break

By default, the progress bar looks something like this:

|#########---------------------|

Methods

set_progress(progress)

Sets the progress on the bar. Should be a float between 0.0 and 1.0.

add_progress(delta)

Adds some progress to the bar. Should be a float less than 1.0.

subtract_progress(delta)

Subtracts some progress from the bar. Should be a float less than 1.0.

Renders the progress bar to output.

If message is set, the progress bar looks like this (for an example of message as "Loading..."):
