heroku_ebooks VS python-getting-started

Hi, I am attempting to create a Markov chain Twitter bot based on a source account (following this guide: https://github.com/tommeagher/heroku_ebooks/) and I am receiving this error after attempting to push to my Heroku app. The runtime.txt document specifies python-3.6.2 needs to be used. Does this error mean that version of Python is not compatible with the heroku-20 stack? I have very little experience with Python and Heroku. I created a similar bot on an old MacBook several years ago but the code reached its end-of-life. Thank you for any assistance.

So recently i want to try making a markov bot from Tommeagher on Github (link and I'm stuck at where you can look it at the photo. any idea?

p.s: here's the link if you need it or ask it Link

For those of you who are new to Python (as I am), I used the Getting Started on Heroku with Python documentation as a helpful guide.

After setting up a Heroku account, we’re nearly ready to deploy. Let’s walk through the steps.

I did set that as the video tutorial from codemy.com that I was watching instructed to do so. But I was able to solve this issue I believe by following the settings.py file on this Github repo (which included moving the whitenoise middleware after the security middleware) and adding STATICFILES_DIRS = BASE_DIR / 'static' (along with deleting the old syntax that I had commented out) while following the steps (including manually running 'python manage.py collectstatic') on this Stack Overflow answer. Now time will tell if the static files will persist or if I will run into an issue when the Heroku dyno restarts.

Here's Heroku's own guide to hosting a python site: https://devcenter.heroku.com/articles/getting-started-with-python
