Capstone Project Problem

I made a mistake in the Email alert code. Now I am currently on the z-score part of the code, where I made another directory. How can I go back and edit my Email alert code? It’s urgent. Please help!!!

cd your_directory_name
Then you will go into your directory

This displays all your saved files in your directory
