[Python-Dev] OSError.errno => exception hierarchy?

Thu Apr 2 14:25:54 CEST 2009

Apologies if this has already been discussed.
I was expecting that by now, python 3.0, the following code:
 # clean the target dir
 import errno
 try:
 shutil.rmtree(trace_output_path)
 except OSError, ex:
 if ex.errno not in [errno.ENOENT]:
 raise
Would have become something simpler, like this:
 # clean the target dir
 try:
 shutil.rmtree(trace_output_path)
 except OSErrorNoEntry: # or maybe os.ErrorNoEntry
 pass
Apparently no one has bothered yet to turn OSError + errno into a hierarchy
of OSError subclasses, as it should. What's the problem, no will to do it,
or no manpower?
Regards,
