How to clean up the Master branch or create a new one to work with a new project? the problem is that you need to start work in a new project, and in the branch the master has history and uncommitted changes from the previous project. How to fix it? how to start a project from scratch? I work in pycharm

Answer 1

Delete the .git folder - this is the repository with your master branch as well.
Delete other unnecessary files in the working directory.
Start a new project in the usual way.

Answer 2

Why not create a new folder with a new project and a new repository?

mkdir my_new_project
cd my_new_project
git init
