What does the error "int object has no attribute __getitem__" mean for this code?
提问by user3235485
I want a loop to create an array of 11 integers y[i]such that y[i] = (i+1)*(i+2)and it gives me an error which I don't understand.
我想要一个循环来创建一个包含 11 个整数的数组，y[i]这样y[i] = (i+1)*(i+2)它就会给我一个我不明白的错误。
In [100]: y = zeros(11)
...: for i in range(11):
...: y[i] = (x[i]+1)*(x[i]+2)
...:
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
<ipython-input-100-7a762b788eff> in <module>()
1 y = zeros(11)
2 for i in range(11):
----> 3 y[i] = (x[i]+1)*(x[i]+2)

xis an integer, notan array:
x是一个整数，而不是一个数组：
>>> x = i = 0
>>> x[i]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'int' object has no attribute '__getitem__'
You need to scan back in your code and see what rebound xto an integer.
你需要扫描你的代码，看看什么反弹x到一个整数。
Your questionhowever implies you think you are executing:
但是，您的问题意味着您认为您正在执行：
y[i] = (i+1)*(i+2)
but your actual code sample clearly shows you are not. Figure out which code should actually run here first.
但您的实际代码示例清楚地表明您不是。弄清楚哪些代码应该首先在这里运行。

Basically that means, that you try to do []on an intso yor xin your code is an integer
基本上这意味着，您尝试[]在intsoy或x在您的代码中做的是integer
