Checkpoint
One last thing before we move on. Same surface as a write step — but the lesson doesn't complete until this passes.
Quick lock-in before lesson two. The code sandbox on this page runs
Python, the language you'll start learning in chapter one. We'll use
it once at the end of each lesson to pin down what you just learned.
Same print() and f-string move you used in chapter zero.
The starter declares three variables that name the parts of lesson
one. Write three print(f"...") lines below them so the output is
exactly:
command: the verb, the thing to do
argument: what the command acts on
shell: the program that reads commands and runs them
The grader runs against these values. You don't need the terminal open for this step. Just type the three lines and run.
