How to remove files from the GitHub repository?

Question

I deleted python .pyc files from my local repo and what I thought I did was to delete from remote github.

I pushed all changes. The files are still on the repo but

Answer 1

git commit -am "A file was deleted"
git push

Answer 2

You should not do git add. That's all

git rm classes/file.pyc
git commit -m"bla bla bla"
git push
