Question

这是我的代码

for i in range(len(speed)):
for j in range(len(time_two)):
    new.append((speed[i] - speed[i-1])/(time_two[j] - time_two[j-1]))

我收到此错误：

ZeroDivisionError                         Traceback (most recent call  
last)
    <ipython-input-7-9cdf386300d7> in <module>()
      4 for i in range(len(speed)):
      5     for j in range(len(time_two)):
    ----> 6         new.append((speed[i] - speed[i-1])/(time_two[j] - 
    time_two[j-1]))

ZeroDivisionError: float division by zero

这里speed和time_two是浮动列表，列表中没有0。

关于我可能会改变什么的任何建议？任何帮助表示赞赏！提前谢谢

编辑：速度= [14.13102608620676， 6.111463527087486， 5.593147106275493， 4.854037993898749，...] time_two = [2.0， 14.0， 15.0， 17.0， 15.0， 15.0 ...]

Answer 1

time_two = [2.0, 14.0, 15.0, 17.0, 15.0, 15.0...]

有两个相同的值，所以如果你这样做

time_two[j] - time_two[j-1]

你得零，所以

(speed[i] - speed[i-1])/(time_two[j] - time_two[j-1])

会触发ZeroDivisionError。

零分割错误，浮点除零
