"Python 3" is just a reminder that version 3 of the Python language is being used. All the courses here use version 3.

And the instructions do not ask you to put exclamation mark after the phrase. It won't cause a problem to have one, but it is not required.

For course challenges, always use what the instructions ask for.

For real projects you would use any punctuation that is appropriate to the message being shown. It's never required for the code to work.

Glad I could help, and happy coding!
