I'm not sure what you are looking for, obviously on OS/2 the C library 
sets errno=10 if a file doesn't exist while all Unix variants I
know of use errno=2 for this purpose.

For portability use the errno module:

Python 1.5.2+ (#4, Nov 18 1999, 01:39:08)  [GCC egcs-2.91.66 19990314 (egcs-1.1.2 release)] on linux2
Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam
IDLE 0.5 -- press F1 for help
>>> import errno
>>> try:
	open('spam','r')
except IOError, x:
	if x.errno == errno.ENOENT:
		print 'Oops'
	else: raise
	
Oops

btw: To get the symbol for an error number use:

>>> errno.errorcode[2]
'ENOENT'
