Found it in the language reference atleast...
http://www.python.org/doc/current/ref/comparisons.html
"The operators in and not in test for set membership. x in s evaluates
to true if x is a member of the set s, and false otherwise. x not in s
returns the negation of x in s. The set membership test has
traditionally been bound to sequences; an object is a member of a set if
the set is a sequence and contains an element equal to that object.
However, it is possible for an object to support membership tests
without being a sequence. In particular, dictionaries support memership
testing as a nicer way of spelling key in dict; other mapping types may
follow suit. "
