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.
