[Numpy-discussion] shuffle a slice

May 29, 2010


      np.random.shuffle: "Modify a sequence in-place by shuffling its contents."

Matches doc string:
...
...
a = np.arange(10)
np.random.shuffle(a[:-1])
a
   array([0, 7, 8, 4, 3, 6, 2, 1, 5, 9])
Doesn't match doc string:
...
...
l = range(10)
np.random.shuffle(l[:-1])
l
   [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
Is there any way for numpy to catch this?
