The column_stack() function in NumPy is used to stack or arrange 1-D input arrays as columns into a 2-D array.
numpy.column_stack(tup)
The column_stack() function takes a parameter value.
tup: This represents a sequence of the 1-D or 2-D arrays to be stacked.The column_stack() function returns an array formed by stacking the input arrays.
import numpy as np# creating input arraysa = np.array([1, 2, 3, 4])b = np.array([5, 6, 7, 8])# stacking the arraysstacked_array=np.column_stack((a,b))# printing the stacked arrayprint(stacked_array)
numpy module.a and b using the array() function.a and b using the column_stack() function. The result is assigned to a variable, stacked_array.stacked_array.
