numpy.column_stack — NumPy v2.2 Manual (original) (raw)

numpy.column_stack(tup)[source]#

Stack 1-D arrays as columns into a 2-D array.

Take a sequence of 1-D arrays and stack them as columns to make a single 2-D array. 2-D arrays are stacked as-is, just like with hstack. 1-D arrays are turned into 2-D columns first.

Parameters:

tupsequence of 1-D or 2-D arrays.

Arrays to stack. All of them must have the same first dimension.

Returns:

stacked2-D array

The array formed by stacking the given arrays.

Examples

import numpy as np a = np.array((1,2,3)) b = np.array((2,3,4)) np.column_stack((a,b)) array([[1, 2], [2, 3], [3, 4]])
