Students write in the course.
The task beside a real editor, with nothing to install.
Your course page, now with a real place to code.
Students write, run and submit their programs inside the lesson. Grades reach the gradebook on their own.
Run shows what it does.
The output appears in the terminal.
Test is practice.
Every check, as often as needed. Nothing is sent to the course.
Your tests stay yours.
Hidden from students; protected ones never reach the browser.
Submit sends the grade.
Graded on the server, sent to the course's gradebook by itself.
One environment for the whole course.

def average(numbers): if not numbers: return 0 return sum(numbers) / len(numbers) print(average([90, 72, 85]))
The program calls average with [90, 72, 85].
Errors, explained.
When a program breaks, a plain-language card says what happened, and where.
def average(numbers): return sum(numbers) / len(numbers) print(average([]))
