Why doesn't Python run on Heroku?

Question

Python

There is the most simple application that displays "Hello World". requirements.txt is, in Procfile.txt:

web: python main.py

All files on the server, git says:

nothing added to commit

In the Heroku web interface under Resources:

This app has no process types yet

Error in logs:

2019-03-26T19:31:23.301424+00:00 heroku[router]: at=error code=H14 desc="No web processes running" method=GET path="/" host=******** .herokuapp.com request_id=10212ad7-0fcb-4141-8292-b9065cb278f9 fwd="31.129.75.92" dyno= connect= service= status=503 bytes= protocol=https

In the FAQ, the solution to problem H14 is to run heroku ps:scale web=1. Trying to run it throws an error:

Scaling dynos... !
! Couldn't find that process type (web).
