No, it doesn't.

>>> s = set(['jan', 'feb', 'mar', 'apr', 'may', 'jun', 'jul', 'aug',
... 'sep', 'oct', 'nov', 'dec'])
>>> 'margarine' in s
False
>>> 'mayonnaise' in s
False
>>> 'octopus' in s
False

True, but my crystal ball tells me that the OP wants exact matches.
(Extrapolating from another post made by the OP earlier today, I'm
guessing he has a list of column names to include in an SQL "order by"
clause, and he wants to check them for validity first.)
