Checkpoint
One last thing before we move on. Same surface as a write step — but the lesson doesn't complete until this passes.
Lesson two lock-in. Back to the Python sandbox for one step.
The starter declares three variables, one per command you learned
for moving around. Write three print(f"...") lines so the output
is exactly:
pwd: prints the folder you are standing in
ls: lists what is inside the current folder
cd: changes which folder you are standing in
The grader runs against these values. Type the three lines, run it, and that's lesson two done.
