It also assumes the user is capable of (1) finding the .py file
(maybe not so easy if it's imported from another program) and
(2) knowing Python well enough to find and understand the line with
the comment. Which in my example is not a problem since I'm probably
the only user of my domaincheck script; but when writing programs
for regular users, when you know an error is both likely and unclear
to read, it might make sense to catch the exception and print
a clearer message.
Your counterarguments are quite valid, though. It's a trade-off.
