Mapping a NumPy array in place Question: Is it possible to map a NumPy array in place? If yes, how? Given a_values – 2D array – this is the bit of code that does the trick for me at the moment: for row in range(len(a_values)): for col in range(len(a_values[0])): a_values[row][col] = dim(a_values[row][col]) But it’s so …
