在Heroku上部署Python App

Question

I created my first chatbot with Chatterbot library. Now I want to deploy it through Heroku, but this is impossible.

My chatbot is composed of some files (py, csv, yml, json, txt). This is the structure:

botusers (csv file)
Magghy (py file)
magghybot (py file)
Procfile
Requirements (txt file)
telegramtoken (txt file)
conversation.yml (in folder named lang)
math_words.json (in folder named lang)

I created a "Procfile" (worker: python magghybot.py) and "Requirements.txt"

Then, I create my Heroku Profile and I tried to deploy my project but on terminal I have this problem:

Counting objects: 13, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (8/8), done.
Writing objects: 100% (13/13), 5.22 KiB | 0 bytes/s, done.
Total 13 (delta 0), reused 0 (delta 0)
remote: Compressing source files... done.
remote: Building source:

remote:

 ! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'https://git.heroku.com/magghy.git'

What am I missing?

You need to set the Python runtime in a runtime.txt file. See here for more details.
