A little nitpick (I wrote try/except some time exact like the above till
I read a posting from Alex Martelli where he wrote about `else' in that
construct); IMO the above code with `else' is clearer:

try:
    fi = open('test.py', 'r')
except IOError:
    print "Can't open file for reading."
else:
    for line in fi:
        print line
finally:
    fi.close()

Now you see at first glance what you try to do, what happens if it fails
and what happens if it succeeds.
