How to rollback commits in git?

Question

git

I am new to git. Yes, and in development in general. I'm taking a video course on django. In the course of the course, I create a site, completely repeating after the teacher, while making commits in certain places. I make several commits in one lesson. Obviously, only by repeating exactly the same, it is difficult to learn something. Therefore, after watching the video, I want to roll back the last few commits and write all the code myself. The question is how to do it.

Answer 1

Roll back three commits:
git reset --hard HEAD~3
In general, you should not blindly repeat commands. It is better to read the documentation and work meaningfully.
