[Numpy-discussion] Method to shift elements in an array?

[Zachary P. <zp...@st...>]

Hello folks,

Does numpy have an built-in mechanism to shift elements along some  
axis in an array? (e.g. to "roll" [0,1,2,3] by some offset, here 2,  
to make [2,3,0,1])

If not, what would be the fastest way to implement this in python?  
Using take? Using slicing and concatenation?
