WEBA trick for doing this is to first mask the array of NumPy “shape-tuples” in places where it equals one. Then, you can check if the peak-to-peak ( np.ptp()) column-wise differences are all zero: Python. >>> masked = np.ma.masked_where(shapes == 1, shapes) >>> np.all(masked.ptp(axis=0) == 0) # ptp: max - min True.
