Checkpoint
One last thing before we move on. Same surface as a write step — but the lesson doesn't complete until this passes.
Lesson one lock-in. Same Python print and f-string move.
The starter declares three variables for real reasons to switch from
one CLI to the other. Write three print(f"...") lines so the output
is exactly:
reason 1: the tool you are using is stuck and you want a fresh take
reason 2: you want a second opinion before trusting a big change
reason 3: one tool is down or slow, so use the one that works
Type the three lines and run it.
