sadmin@247CodeGirl if you factor in list/set creation time, there is no clear winner:
import timeit
for size in [5, 10, 20, 50, 100, 1000]:
list_time = timeit.timeit(
lambda: (size - 1) in list(range(size)),
number=100000
)
set_time = timeit.timeit(
lambda: (size - 1) in set(range(size)),
number=100000
)
faster = "SET" if set_time < list_time else "LIST"
ratio = max(list_time, set_time) / min(list_time, set_time)
