It looks even more like an expression without any embedded colons ;)
def greet(person=None):
# Infix conditional
print "Hello %s" % ("World" if person is None else person)
def greet(person=None):
# Negated infix conditional so that 'normal' value is first
print "Hello %s" % (person if person is not None else "World")
def greet(person=None):
# Prefix conditional
print "Hello %s" % (if person is None then "World" else person)
Anyway, Guido's already given some indication that the PEP 308 infix and
prefix conditional operators without colons (above) are the main options he is
considering choosing from.

Nick.
