I have a general question of Python style, or perhaps just good
programming practice.
My group is developing a medium-sized library of general-purpose
Python functions, some of which do I/O. Therefore it is possible for
many of the library functions to raise IOError Exceptions. The
question is: should the library function be able to just dump to
sys.exit() with a message about the error (like "couldn't open this
file"),
No

Yes -- with an informative error message.
If the caller ignores the exception, the program will exit with a full
stack trace anyway.
