“‘While”循环计数是否有效？

Question

ans = num_rushes(100, 15, 7)
print(ans) 

应该返回19，但我的返回12？

这就是我所拥有的：

def num_rushes(slope_height, rush_height_gain, back_sliding):
    rushes = 0
    current_height = 0
    rush_height_counter = 0
    back_sliding_counter = 0
    rush_height_gain = 0.95 ** rush_height_counter * rush_height_gain
    back_sliding = 0.95 ** back_sliding_counter * back_sliding

    while current_height < slope_height:
        current_height = current_height + rush_height_gain
        rushes += 1
        rush_height_counter += 1
        back_sliding_counter += 1

        if current_height < slope_height:
            current_height = current_height - back_sliding

        else:
            return rushes

Answer 1

使用这段代码0.95 ** rush_height_counter * rush_height_gain，您的意思是

0.95 ** (rush_height_counter * rush_height_gain)

或

(0.95 ** rush_height_counter) * rush_height_gain

我想你想要第一个，但是python (据我所知)做第二个！
