Sure. The following is, I believe, self-explanatory:

>>> try:
... 	raise TypeError
... except ValueError:
... 	print "Got a ValueError"
... except TypeError:
... 	print "Got a TypeError"
... 	
Got a TypeError

You can also "catch" the exception object itself:

>>> try:
... 	raise TypeError("This is a type error")
... except TypeError, e:
... 	print "TypeError found!"
... 	print "Error: %r." % e
... 	print "Arguments of exception object: %r." % e.args
... 	
TypeError found!
Error: <exceptions.TypeError instance at 0x010DD530>.
Arguments of exception object: 'This is a type error'.

Hope it helps, with my best regards,
