single positional indexer is out-of-bounds

This error message usually occurs when you try to access an index that is not within the bounds of a data structure. For example, if you have a list with only three elements and you try to access the fourth element with an index of 3, you will get this error message.

To fix this error, you need to make sure that the index you are trying to access is within the bounds of the data structure. You can do this by checking the length of the data structure and making sure that the index is less than the length minus one.

Here's an example of how to fix this error when working with a list:

my_list = [1, 2, 3]

# This will raise a "single positional indexer is out-of-bounds" error
# because the index 3 is out of bounds
print(my_list[3])

# To fix the error, we need to make sure the index is within bounds
if len(my_list) > 3:
    print(my_list[3])
else:
    print("Index is out of bounds")

In this example, we check the length of the list before trying to access the fourth element. If the length is greater than three, we can safely access the element at index 3. If the length is less than or equal to three, we print an error message instead.
