[Numpy-discussion] put with increment ?

Hello everyone, Is there a 'numpy' efficient way to do the following loop: for i, v in indices, values: total[ i ] += v The behaviour is like numpy.put, but instead of overwriting the array element, it is incremented. Currently I have a little C extension which does the job, but I'm lazy to fix it up for all the various dtypes etc. Am I missing a more general way? I have repeated values in indices, so that: total[indices]+=values ... does not give the result I'm after. Thanks Jon
