[Zope] python question

[Jürgen Herrmann]

hi all!

i think there should be no functional difference in the two code snippets
below, but is there any difference in performance?
(i know, the "except AttributeError" could possibly mask an AttributeError
in the called function...)

1.:
hook = getattr(o, '_before_transaction_commit', None)
if hook: hook()

2.:
try: o._before_transaction_commit()
except AttributeError: pass

regards, juergen herrmann
