How do I update a command in git?

Question

I am totally new to git and heroku. I am trying to deploy an app to heroku but there was a problem and I later realized that I ommitted ':' from my if statement in my python script. I have made the necessary correction, but the deployment is still not successful. I have already run this command git add app.py in my powershell, but I think I am supposed to make an update of this command. Is there a way to make the update or do I run the git add app.py command again?

I am using Microsoft Windows Powershell on Windows 10, and using git version 2.28.0. Thanks for your help.

Answer 1

I think you forgot to commit after adding to staging area

run the following command:

$ git add <filename>
$ git commit -m "your message if any"
$ git push heroku master

Answer 2

As you didn't commit your change your changes have not saved to your local repository. So just commit your changes. just follow:

git add app.py
git commit -m "your message"
git push heroku master
