Line 18 in 22e8f0b

python-version: 3.7

Probably should be updated?

Hi @ricardoV94 @maresb I am at the Code Sprint (PyData London) looking for issues to work on.

I think this could be closed as well. Looks like the python-version was removed in #7622 along with the entire Set up Python step.

Awesome, it's great to see our issue count going down!
