Something like def calculate(params): a = b = 0 if some_calculation(params): a += 1 if other_calculation(params): b += 1 return (a, b) alpha = beta = 0 temp_a, temp_b = calculate(...) alpha += temp_a beta += temp_b Is there a better way to do this without holding each temporary result before using it to increment? -tkc
