For the exactly equal case, how about: I[1] a = np.array([1,1,1,1]) I[2] np.unique(a).size O[2] 1 # All equal I[3] a = np.array([1,1,1,2]) I[4] np.unique(a).size O[4] 2 # All not equal _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
