Before You Begin

Execute cd by itself in your terminal window. You should find that your terminal window's prompt resembles the below:

$

Starting Each Problem

For each problem, you'll follow this same pattern. Here's an example for the first problem:

Step 1: Create a folder

mkdir indoor

Step 2: Navigate into the folder

cd indoor

You should now see your terminal prompt as indoor/ $

Step 3: Create your Python file

code indoor.py

This will open a new file where you'll write your program.

Repeat for Each Problem

Follow the same pattern for all five problems:

• indoor → indoor.py
• playback → playback.py
• faces → faces.py
• einstein → einstein.py
• tip → tip.py

Submission

When you've completed all five problems:

1. Test each program thoroughly
2. Commit your changes: git add . then git commit -m "Complete Week 0"
3. Push to GitHub: git push

Your submission will be automatically recorded when you push to your repository.
