Everything with "except:" is done if that exception is matched. A
"finally:" clause is executed regardless of whether an exception
was raised. If you have an "except:" clause already, that's quite
superfluous.

Ideally, I would like to do

How about:

try:
    f1 = open(file1)
	(etc)
except: 
    print 'File open error'
f1.close()

It will always get there.

(Of course, no need to close files - it'll be done automatically after the
file leaves scope, because of refcounting)
