By the way, alternative options would be:

>>> append = True

>>> append and 'a' or 'w'

'a'

>>> append = False

>>> append and 'a' or 'w'

'w'

Of course, the

>>> 'a' if append else 'w'

is nicer, but has only been supported for python 2.5+.

An alternative, third, method, would be

>>> append = True

>>> ['w', 'a'][append]

'a'

>>> append = False

>>> ['w', 'a'][append]

'w'

No reason to change the working code, of course, but just possibilies to keep in mind.
