Look at the code again. It's not testing what it says it's
testing.
print "\nRandom access to first item in list/set"
t1=timeit.Timer("0 in z","z = set(xrange(10000))")
t2=timeit.Timer("0 in z", "z = list(xrange(10000))")
print "set ->", t1.timeit(1000)
print "list ->", t2.timeit(1000)
print "\nRandom access to item in list/set when item exists"
t1=timeit.Timer("500 in z","z = set(xrange(10000))")
t2=timeit.Timer("500 in z", "z = list(xrange(10000))")
print "set ->", t1.timeit(1000)
print "list ->", t2.timeit(1000)
