Do you know "sample[::-1]" mean? in Python

Question

In Python, I don't know the meaning of the following usage:

sample[::-1]

Who knows that? Do you know what [::-1] means?

This might come as a surprise, but [googling `python colon colon negative one`](https://www.google.com/search?q=python+colon+colon+negative+one) actually turns up the answer to this question immediately. — user2357112, May 02 '16 at 05:37
