There's trouble there, though:

Python 2.6.5 (r265:79063, Apr 16 2010, 13:09:56) 
[GCC 4.4.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> f = open ('xyzzy.txt')
>>> f.name
'xyzzy.txt'
>>> import os
>>> os.getcwd()
'/home/mwilson'
>>> os.chdir('sandbox')
>>> f.name
'xyzzy.txt'


If you open a file and don't get a full path from os.path.abspath right 
away, the name in the file instance can get out-of-date.
