IndexError: indices are out-of-bounds
时间: 2024-01-24 13:19:41 浏览: 41
这个错误通常意味着你正在尝试访问一个不存在的索引位置。这可能是由于以下原因之一:
1. 索引超出了列表或数组的范围。例如,如果你有一个长度为 5 的列表,但尝试访问第 6 个元素,则会发生此错误。
2. 索引是负数。在某些编程语言中,负数索引表示从列表或数组的末尾开始计数。如果你使用了负数索引并且计算出的索引值超出了范围,则会发生此错误。
3. 索引是非整数。索引必须是整数,如果你使用了浮点数或其他类型的数据作为索引,则会发生此错误。
要解决此错误,你需要检查代码中的索引值是否在列表或数组的范围内,并确保索引是整数。如果使用负数索引,请确保计算得到的索引值也在范围内。

IndexError: single positional indexer is out-of-bounds
This error occurs when you try to access an element of a list or array using an index that is outside the range of valid indices for that list or array.
For example, if you have a list with 5 elements and you try to access the 6th element using an index of 5, you will get an IndexError because the index is out of bounds.
To fix this error, you need to make sure that the index you are using is within the range of valid indices for the list or array. You can do this by checking the length of the list or array and making sure that the index is less than the length.
raise IndexError("single positional indexer is out-of-bounds") IndexError: single positional indexer is out-of-bounds
This error occurs when you try to access an index that does not exist in a list, tuple or other iterable.
For example, if you have a list `my_list` with only 3 elements, and you try to access the 4th element using `my_list[3]`, you will get this error because the index is out of bounds (i.e. it exceeds the range of valid indices for the list).
To fix this error, you need to make sure that you are using valid indices for the iterable you are working with. For example, if you want to access the last element of a list, you can use the index `-1` instead of trying to guess the length of the list and accessing it with an index that may be out of bounds.
