list = [ "they", "that", "tommy" ]
word = raw_input( "Enter the word > " )
filter( lambda x, w = word: not x.find( w ), list )

   or, for Python < 2.0:

from string import find
filter( lambda x, w = word: not find( x, w ), list )

   or (could it be faster? :-\) :

filter( lambda x, w = word: x[ :len( w ) ] == word, list )
