Hi, Python is optimized for performance. Formatting an error message has a cost on performances.
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.
