These methods are part of what is known as "magic" in Python, as they allow objects to customize ... analysis tools to detect type errors before the code is run. The Matrix class in Python implements ...

so they aren’t constrained by Python’s limitations. NumPy provides a specialized array type that is optimized to work with machine-native numerical types such as integers or floats.

Build up all the combination of 3*3 magic matrix. mm.append(np.flipud(mag_matrix)) mm.append(np.flipud(mag_matrix).T) mm.append(np.fliplr(mag_matrix)) mm.append(np ...
