Almost anything which says "Errno ..." is almost always an OSError (or an
IOError as I found the other day). I try to be quite picky about these. So for
example:
try:
fp = open(filename)
except OSError as e:
if e.errno == errno.ENOENT:
# file missing
... act as if the file were empty ...
else:
# other badness - let the exception escape
raise
