tqdm looks super promising. progressbar and progressbar2 end up being complicated and weird enough to use that my company ended up making wrappers. Why maintain that when you can just use a library that works out of the box.<p>It would be great if it had ipython notebook support. I often end up doing long operations that scrape services for data but have no idea what their progress is.<p>For me 2015 has been the year of tox. It is a great tool and worth using for just about any python project.
