For what purpose would this be handy? Surely the benefit of the
interactive interpreter is that you can simply try it out and *see*
what happens.
But, in case it helps: Any code may raise any exception at any
time. This is a feature, since it encourages program that are tested
properly.
That's a silly argument, really, unless perhaps you'd consider a box of
pills that look like M&Ms a 'feature' since it encourages parents to
hide them from their kids. A better answer would be along the lines of
"yes, that would be nice to have but in general it's not possible in a
dynamic language; that's the price you have to pay for leaving the
static typing world".
As for the OP's question, since file is a fixed builtin, I think it
should be possible to know all the possible exceptions that can be
raised; I'm not sure if it's clearly documented though.
