python-progress 1.5 seems to break pip.
Downgrading to python-progress 1.4 fixes it.

Additional info:
* package version(s) 18.1-1

Steps to reproduce:
pip -h
Traceback (most recent call last):

Note that python-pip is also substantially out of date.

A workaround that worked for me (might be useful for others)
- uninstall pip
- remove the folder "/usr/lib/python3.7/site-packages/pip/"
- reinstall pip

One big difference between a fresh install after deleting manually the folder and keeping it, is that the "_vendor" subfolder does not contain "progress" any more (and pip is now working perfectly).

_vendor should not contain anything unless you broke your installation by using sudo pip install pip, in which case no guarantees can be made of anything at all, ever. If so, pleas pacman -S lostfiles and run the lostfiles script to find files in your /usr that do *not* belong there.

At any rate, pip is now updated to work with progress 1.5, so this is no longer an issue.
