What you are describing does not sound like the sort of error the Python
shell will give. Are you able to copy and paste the student's exact input
and output, including the complete error message?

If not, can you take a screenshot and post that?

(As a general rule, we prefer text-based communication rather than pictures.
For all we know, there could be blind or other visually-impaired users on
this forum who can read text via a screen reader, but cannot contribute
when it is a screenshot. But if all else fails, a screenshot is better than
nothing.)

We would love to help you, but without further information we have no idea
what is going on. The more concrete information you can pass on to us, the
better.

Regards,


Steve
