Python warm-up

~12 min

Run Python three ways in the practice shell.

Use the in-page practice shell (or the full VM) for these drills.

Check the interpreter: python3 --version
Explore the sample app: cat ~/projects/app/app.py
Run a script: python3 ~/projects/app/app.py (the shell shows its print output)
Create your own: echo 'print("deploy ok")' > ~/hello.py then python3 ~/hello.py
Inspect what you made: ls -la ~ and cat ~/hello.py

Everything here works in the simulated shell; the full VM gives you the real REPL when you want it.
