索引100超出尺寸100的轴0的范围 [英] index 100 is out of bounds for axis 0 with size 100

问题描述

我正尝试使用python编写一个程序来计算

I was trying to write a programme using python to compute the infinite series of

1/1 ^ 2 + 1/2 ^ 2 + 1/3 ^ 2 + 1/4 ^ 2 + .....

1/1^2 + 1/2^2 + 1/3^2 +1/4^2 +.....

我的代码如下：

n = 100
x = np.zeros([n])
x[0] = 0
for i in range(n):
   x[i+1] = x[i] + 1/float((i+1)**2)
print x[99]

当我尝试执行代码时，它返回以下内容：

when I tried to execute the code, it returned something as:

IndexError：索引100超出了轴100的大小100的范围

IndexError: index 100 is out of bounds for axis 0 with size 100

知道代码有什么问题。谢谢！：）

I would like to know what is wrong with the code. Thanks!:)

推荐答案

索引 i 升至 99 ，因此您尝试在最后一次迭代中获得 x [i + 1] == x [100] 不起作用，因为 x 升至 x [99]

Index i goes up to 99 so you are trying to get x[i + 1] == x[100] at the last iteration, so it can not work because x goes up to x[99]

在您的for循环中只需执行 range（n-1）

In your for loop just do range(n - 1)
