Normally you'd define a function doing the search and use it.
Don't be afraid to use more lines if your code is clear.
First, avoid using list as a name, it is already defined.
Second, None is the standard constant not really anything value.
def missing(element, source):
for part in source:
if element == part:
return False
return True
vehicles = ["airplane", "car", "boat"]
select = None
while missing(select, vehicles):
select = raw_input("Which vehicle?")
For this particular test, there happens to be an idiom you can use:
vehicles = ["airplane", "car", "boat"]
select = None
while select not in vehicles:
select = raw_input("Which vehicle?")
