Lesson Briefing

Pyfessor

"Imagine writing 200 lines of code today, then coming back to it in three weeks. Will you remember what every line does? Probably not. Comments are notes you leave in your code that Python completely ignores — they're just for humans. Professional programmers write comments constantly. It's one of the habits that separates good developers from great ones, and it costs you nothing."
