Hi,
Python is optimized for performance. Formatting an error message has a cost on performances.
Usually, when an exception is hit that will (probably) crash the program, no one cares about less than a microsecond of performance.
I suggest you to teach your student to use the REPL and use a custom exception handler: sys.excepthook: https://docs.python.org/2/library/sys.html#sys.excepthook
Using a custom exception handler, you can run expensive functions, like the feature: "suggest len when length is used".
The problem is then when students have to use a Python without the custom exception handler.
