I am trying to run a python file on my heroku. I tried not setting a build pack as well as setting one and neither seems to work. The only files in my branch are a .py and the .git folder Here is an error example:
Enumerating objects: 3, done.
Counting objects: 100% (3/3), done.
Delta compression using up to 4 threads
Compressing objects: 100% (2/2), done.

You need the following 2 files additionally in your git repo: runtime.txt and requirements.txt
runtime.txt is responsible for which Python version your program is going to use.
cat runtime.txt
python-3.7.2
supported runtime.txt version changes from time to time so check out https://devcenter.heroku.com/articles/python-runtimes
requirements.txt is needed to specify which libraries from https://pypi.org/ your project is depending on. Be sure to specify a version to avoid breakage.
You can get a list of your currently installed python libraries with the command: python -m pip freeze > requirements.txt
