How to update one NumPy array with values from a different array?

Question

If I had two different arrays with different dimensions like the following:

loaded_data = np.arange(4674).reshape(57, 41, 2)
final_data = np.zeros((60, 41, 2))

How would I most efficiently update final_data with the values from Loaded_data leaving the additional columns with zero value?

You can use array slicing to do the update

final_data[:loaded_data.shape[0]] = loaded_data
