Also, in a common use-case, bitwise-and behaves the same as logical_and, e.g. if (arr > x) & (arr2 == y) This "works" because both arrays being bitwise-anded are boolean arrays. So you really don't need to call: np.logical_and and friends very often. so -1 on yet another set of operartors. -CHB -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception chris.bar...@noaa.gov
