How to Catch 2 Exceptions at once?

[Gregory Piñero]

How can I catch 2 exceptions at once for example:

try:
self.gses = opener.open(req )
except (urllib2.HTTPEr ror,urllib2.URL Error):
do something..

Seems to work, but how do I also get information about the error?

pytry:
.... raise ValueError, 'Illegal value for your shoe size!'
.... except (IndexError, ValueError), e:
.... print e
....
Illegal value for your shoe size!

Errr .. the same way as if you mentioned only one exception. The
following is an expansion of the scarcely-describable-as-bare coverage
in the tutorial
(http://docs.python.org/tut/node10.ht...000000000000):

C:\junk>cat gregpexc.py
import sys
try:
fname = raw_input('File name:')
f = open(fname)
i = 1 / 0
# except IOError, (errno, strerror):
# print "I/O error(%s): %s" % (errno, strerror)
except (IOError, KeyboardInterru pt, ZeroDivisionErr or), e :
print repr(e)
print e
print dir(e)
print e.args
print e.__class__.__n ame__
except:
print "Unexpected error:", sys.exc_info()[0]
# no example shown; read the fine manual :-)
raise

C:\junk>python gregpexc.py
File name:<exception s.KeyboardInter rupt instance at 0x00AF1EE0>

['__doc__', '__getitem__', '__init__', '__module__', '__str__', 'args']
()
KeyboardInterru pt

C:\junk>python gregpexc.py
File name:kl;lklklkl k
<exceptions.IOE rror instance at 0x00AF1F08>
[Errno 2] No such file or directory: 'kl;lklklklk'

'errno',
'filename', 'strerror']

C:\junk>python gregpexc.py
