I\'m trying to find a short way to see if any of the following items is in a list, but my first attempt does not work. Besides writing a function to accomplish this, is the
>>> L1 = [2,3,4] >>> L2 = [1,2] >>> [i for i in L1 if i in L2] [2] >>> S1 = set(L1) >>> S2 = set(L2) >>> S1.intersection(S2) set([2])
Both empty lists and empty sets are False, so you can use the value directly as a truth value.
