Write a NumPy program to create two arrays with shape (300,400, 5), fill values using unsigned integer (0 to 255). Insert a new axis that will appear at the beginning in the expanded array shape. Now combine the said two arrays into one. Sample Solution: Python Code: # Importing NumP...

For two-dimensional arrays: Python Copy x = [[1, 2], [3, 4]] np.concatenate([x, x], axis=1) Here's the output: Output Copy array([[1, 2, 1, 2], [3, 4, 3, 4]]) Notice that the axis=1 parameter makes the concatenation occur along columns rather than rows. Concaten...
