Code LV

Just a simple test to see which is faster... the winner using in! %%timeit x = 3 x in [1,2] 10000000 loops, best of 3: 53.6 ns per loop %%timeit x = 3 x==1 or x==2 10000000 loops, best of 3: 61 ns per loop %%timeit x = 3 x in [1,2] 10000000 loops, best of 3: 51.5 ns per loop %%timeit x = 3 x==1 or x==2 10000000 loops, best of 3: 56.2 ns per loop %%timeit x = 3 x==1 or x==2 or x==3 10000000 loops, best of 3: 76.2 ns per loop %%timeit x = 3 x in [1,2,3] 10000000 loops, best of 3: 52.2 ns per loop %%timeit x = 3 x==1 or x==2 or x==3 or x==4 10000000 loops, best of 3: 86 ns per loop %%timeit x = 3 x in [1,2,3,4] 10000000 loops, best of 3: 51.5 ns per loop Clearly using the "x in list"format is faster.
