Heroku updates to python

If you see a message like this during one of your heroku builds/pushes, here’s what you should do:

remote: -----> Python app detected
remote:  !     Python has released a security update! Please consider upgrading to python-3.7.7

Take a look at what your runtime.txt file looks like. Mine looks like:

$ more runtime.txt
python-3.7.6

So, fire up your favorite editor and make it match.

Then commit that file, and push it back up to your repo and heroku.

$ git push heroku master
