numpy.column_stack(tup)
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
. 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 arrayThe array formed by stacking the given arrays.
Examples
>>> importnumpyasnp>>> a=np.array((1,2,3))>>> b=np.array((4,5,6))>>> np.column_stack((a,b))array([[1, 4], [2, 5], [3, 6]])
