Thank you for the notes, Anjali!
I have merged and pushed the file again to Git. However, similar to last time, the Jupyter file is not opening, so I couldn't check if the file got updated. Please let me know if it's still the same.

Thanks, Anjali, for providing the commands.
I've made the changes, please let me know if anything else needs to be changed.

I have a few questions that I'd like to ask once you confirm there are no further changes, to avoid any confusion.

Your command:
git checkout assignment-2
git checkout main -- assignment_1.ipynb
git add assignment_1.ipynb
git commit -m "Revert assignment_1.ipynb to main branch"
git push origin assignment-2

1. I was under the impression that a file gets pushed to Git after the 'git push' command. However, with git push origin assignment-2, it didn't push the assignment-2 file to the assignment-2 branch.
2. With git commit -m "Revert assignment_1.ipynb to main branch", did it push the file? Because I see that the file got updated now. So, does the 'commit' command also serve the function of the 'push' command?

1. git push origin assignment-2: This command pushes your local assignment-2 branch to the remote repository (GitHub in your case). It doesn't push any individual files directly. It pushes the entire branch with all changes (committed files) to GitHub.

2.git commit -m "Revert assignment_1.ipynb to main branch": This command only commits changes to your local repository. It does not send anything to GitHub. The commit operation records changes to the file (assignment_1.ipynb in this case) in your local branch (assignment-2), but it stays on your local machine until you push it to GitHub.

git push origin assignment-2: This pushes your local branch (assignment-2) to the remote repository (GitHub). This command uploads the committed changes (like the updated assignment_1.ipynb file) to GitHub, making them available on the remote repository.

The command git checkout main -- assignment_1.ipynb checks out the file assignment_1.ipynb from the main branch and places it in your current working directory on your assignment-2 branch. This is why you see the file updated locally.
After that, you run git add assignment_1.ipynb to stage the file (marking it for commit), and git commit actually records that change in the local branch.

I hope I have answered your question

Thanks a ton Anjali :)
