 I start to learn python from 《Numpy Beginner's Guide》second edition  written by Ivan Idris
now I know what the problem is ,the reason is that  Numpy converts 2000 to an `int32`.When I use code `a=np.arange(2000, dtype='int64')**3 that you taught me, the calculation is correct thank you all ! Yuping Wang
