[Tutor] Universal error handler

Thats pretty much a description of try/except handling style but...

It looks a lot like what you asked for! What do you find
disfunctional? Is it the call to the main function?

You could just write the code:

try:
    # contents of main here
except EOFError:
    # error code here

But I assume you realised that, son what exactly do you
find amiss? I'm a wee bit confused.

But your post worked - it got a response, cxongratulations,
welcome to the community :-)
