    • Try running git status. What do they see? Why?
    • Initialize a repository by running git init
    • Re-run git status. Is it better now?
    • Start version-control the my_code.py file.
    • Commit a change to the my_code.py file.
    • Check the logs using git logs. What do they see?

  • Exercise 2 (exercise_2) - Logs & checkout: In this exercise, students are asked to:

    • Explore the logs with git checkout to find out what was inside three files that used to be there in the past.

  • Exercise 3 (exercise_3) - Branching & merging: In this exercise, students are asked to:

    • Create a branch with git branch
    • Make some changes to the available files

    • With the ls -a command, locate the folder where all the Git magic happens.
