ipy-progressbar's Introduction

Introduction

ipy-progressbar allows to use the same code for rich progressbars in IPython Notebooks, and for simple fallback ones in terminal sessions.

Example

Code like this:

from ipy_progressbar import ProgressBar

pb = ProgressBar(10, title='Outer')
pb_inner = ProgressBar(5, title='Inner')
for i in pb:)
    for j in pb_inner:
        # inner loop body

will work both in IPython Notebook and in plain console. When run in notebook, the output will be rich (Bootstrap progress bars), while console version is mainly thought of as a fallback.

For more examples see example.py and example.ipynb.

Problem with Notebook 5.0.0

Hi,
I have following problem. I updated Jupyter Notebook to version 5.0.0 and ipywidgets to 6.0.0.
The results is that error. I hope that this project is still active.
