On the contrary, it is exquisitely Pythonic.  You used the magic word
yourself:  _membership_.  A string is a sequence of characters, so when
testing membership with the `in' operator, the left-hand side of the
expression should be a character (really a string of length one).  `in'
tests membership, not for the existence of subsequences.  Would you have
expected

	[1, 2] in [1, 2, 3, 4]

to evaluate to true?
