It seems trivial in this example to break it into two try blocks:
try:
name = input("Enter file name, or Ctrl-D to exit")
# On Windows, use Ctrl-Z [enter] instead.
except EOFError:
sys.exit()
try:
fp = open(name)
except IOError:
handle_bad_file(name)
else:
handle_good_file(fp)
But if the code's more complicated and it's not so easy to split, then
sure, doesn't seem a problem. It's like spam[foo//bar] and then
catching either IndexError or ZeroDivisionError - there's no big
confusion from having two distinct sources of two distinct errors
handled by two distinct except blocks.
