Arguably more readable, but arguably less idomatic, is to describe the
actual condition that controls the loop in a string (non-empty strings
are equivalent to True in this context):
while "there is more input":
rval = parse(raw_input())
if real is None:
print('foo')
else:
print('bar')
(Although now that I've said that, this looks like an infinite loop
unless parse, raw_input, or print raises an exception.)
