I think that's an anti-pattern (because of the repetition, as you say). An improvement:: value = some_default_value_such_as_None while value in undesired_values: value = get_some_value() More common and generally useful:: while True: value = get_some_value() if value not in undesired_values: break > What are other's thoughts on this?
