How to remove every other element of an array in python? (The inverse of np.repeat()?) -


if have array x, , np.repeat(x,2), i'm practically duplicating array.

>>> x = np.array([1,2,3,4])     >>> np.repeat(x, 2) array([1, 1, 2, 2, 3, 3, 4, 4]) 

how can opposite end original array?

it should work random array y:

>>> y = np.array([1,7,9,2,2,8,5,3,4])   

how can delete every other element end following?

array([7, 2, 8, 3]) 

y[1::2] should job. here second element chosen indexing 1, , taken @ interval of 2.
