Besides sorting the data itself, sometimes we need to obtain the indices that would sort the index. Consider a Pandas Series with the index out of order. Our objective is to sort this Series by its index and additionally get the index positions that would sort the Series. This technique first resets the index, moving it into a column, and then sorts by that column. It returns a DataFrame with sorted values and original indices. This is a more manual approach but allows for additional flexibility if needed, such as custom sorting logic. By using the sorted function with a lambda, we can specify a custom sorting function—here, one that sorts the indices. Then, we use these sorted indices to rearrange the original Series.
