AFAIK this would produce exactly the same result as what your code does: state_function(state,weight,value) state[0] = state[0]+weight state[1] = state[1]+weight*value final_function(state) return state[1]/state[0] The state[0] is the same as your _sumedWeight. Because it's a constant in the second loop you can do the division after. state[1] is your _sumedWxV times _sumedWeight. Have a nice day, |
