[Chicago] Easier way of finding sha256 of python packages

[Joshua Herman]

So currently I am working on a python project where I have a
requirements.txt which is also enforcing that the hashes of the python
packages that are in the project being verified. When I install a
python package I have to get the hash to put it in the
requirements.txt I was wondering if there is a better way of doing
this than doing the following.

1. Download the package I want to add to my project from pip.
2. Run pip hash on the downloaded file .
