This is a really nice feature. GHC and Clang do it for several things 
and it usually helps (when a live highlighter isn't available).

Given that these are HS students, presumably seeing Python for the first 
time, shouldn't they be using PyCharm to get used to PEP 8 (no l[10]=14) 
and other best practices (e.g., such as using 'with' instead of 
'try/finally' when possible)? This would provide live syntactic (and 
some semantic) highlighting with short human-readable messages.

Overall, I already find Python's exceptions quite readable, and your 
suggestions propose some VERY long lines which would certainly wrap at a 
terminal. Maybe this should be an optional feature.
