find it hard to imagine use cases where "file = open(thisfile) or open(thatfile)" makes sense. Not even for the case where thisfile == 'script.pyc' and thatfile == 'script.py'.
Counterexamples - any configuration file: a program looks for its config at $HOME and not finding it there looks in /etc. So config = open('~/.someprogram.config') or open('/etc/someprogram/config') would make sense.
A counterexample with gethostbyname - a list of proxies. It's not an error if some or even all proxies in the list are down - one just connect to the first that's up. So a chain like proxy_addr = gethostbyname(FIRST) or gethostbyname(SECOND) would make sense.
