Its my first attempt to deploy a python program to Heroku.

My python program was

name=input("What is your name?: ");
print("Nice to meet you", name)  

and https://shielded-gorge-83102.herokuapp.com/says

Application error 
An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details. You can do this from the Heroku CLI with the command
heroku logs --tail 

On executing logs command:

I read this post: App crashing on Heroku Pyphon application

and it says you cant use input command here. So is this because it is a web app and print command cant run on browser? Please tell me how to run this program without taking input.

So, if we need a bit HTML here, I also know working with HTML. So please help me with running this program using python.

You can still have input, but in a bit different way. Check out this Send data from a textbox into Flask?

Then once you have a simple app follow this tutorial to get it deployed https://devcenter.heroku.com/articles/getting-started-with-python

Most likely you know most of the steps already. Also not all of them are mandatory.
