Splitting columns of a numpy array easily

Question

How can I split an array's columns into three arrays x, y, z without manually writing each of the [:,0],[:,1],[:,2] separately?

Example

# Create example np array
import numpy as np
data = np.array([[1,2,3],[4,5,6],[7,8,9]])

Now data is

[[1 2 3]
 [4 5 6]
 [7 8 9]]

What I want to do:

x, y, z = data[:,0], data[:,1], data[:,2] ## Help me here!
print(x)

Wanted output:

array([1, 4, 7])

Answer 1

Transpose, then unpack:

>>> x, y, z = data.T
>>> x
array([1, 4, 7])
