How to deploy python modules on Heroku?

Assuming you have set up Python 3.6, Pipenv and heroku CLI installed locally and are logged in on Heroku from the CLI using the steps mentioned here: https://devcenter.heroku.com/articles/getting-started-with-python#set-up.

Your application needs to have a git repository to be deployed to heroku. You need to cd in the directory where the root of your git repo code resides. Now you need to create a heroku application using:

$ heroku create
Creating lit-bastion-5032 in organization heroku... done, stack is cedar-14

http://lit-bastion-5032.herokuapp.com/ | https://git.heroku.com/lit-bastion-5032.git

Git remote heroku added

When you create an app, a git remote (called heroku) is also created and associated with your local git repository. Heroku generates a random name (in this case lit-bastion-5032) for your app, or you can pass a parameter to specify your own app name.

Now that a remote has been added, you can push your code to heroku using:

$ git push heroku master

Note that you need to specify your requirements(third party modules you are importing) with their version numbers(or without if you need latest one) in the requirements.txt. For example,
Flask==0.8
Jinja2==2.6
Werkzeug==0.8.3
certifi==0.0.8
chardet==1.0.1
