IndexError: index 2 is out of bounds for dimension 0 with size 2
时间: 2024-01-03 15:03:01 浏览: 26
This error occurs when you are trying to access an element of a list or array using an index that is out of range. In this case, the size of the array is 2, but you are trying to access the element at index 2, which does not exist.
For example, if you have a list with two elements:
```
my_list = [1, 2]
```
And you try to access the third element:
```
print(my_list[2])
```
You will get the IndexError because there is no element at index 2.
To fix this error, make sure that you are using valid index values that are within the range of the list or array.

IndexError: index 2 is out of bounds for dimension 0 with size 1
这个错误通常表示你正在尝试访问一个数组、列表或其他序列类型的索引,但是这个索引超出了序列的范围。例如,如果你有一个长度为 `1` 的数组,但是尝试使用索引 `2` 来访问它,就会出现这个错误。
下面是一个示例代码,演示了这个错误的出现情况:
```python
my_list = [1]
print(my_list[2])
```
在这个例子中,`my_list` 是一个长度为 `1` 的列表,但是我们尝试使用索引 `2` 来访问它,因此会出现 `IndexError: index 2 is out of bounds for dimension 0 with size 1` 错误。
要解决这个错误,你需要确保你的索引值不超过序列的长度。你可以使用 `len()` 函数来获取序列的长度,并在访问序列元素时进行检查。例如,你可以这样写:
```python
my_list = [1]
if len(my_list) > 2:
print(my_list[2])
else:
print("Index out of bounds")
```
这个代码片段将输出 `Index out of bounds`,因为长度为 `1` 的列表中没有索引为 `2` 的元素。
IndexError: index 85 is out of bounds for dimension 0 with size 85
IndexError: index 85 is out of bounds for dimension 0 with size 85错误是由于索引超出了数组的长度导致的。具体来说,在这个错误中,索引85超过了数组的最大索引值,数组的长度为85,因此最大索引应该是84而不是85。这意味着您正在尝试访问数组中不存在的元素。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
