# Try it yourself
Try executing the code below to verify the results:

pali = 'Was it a cat I saw?' 
print(pali[::-1])

> “Was it a cat I saw?” is a palindrome. A palindrome can be read the same backward and forward.


# Explanation

This is the best way to reverse a string in Python (`pali[::-1]` is a string slice). Slices have `start`, `stop`, and `step`—each of them optional. One **half-open range**, meaning we’ll get from the first index up to but not including the last, is `start` to `stop`. Additionally, if we specify a negative stop, it’ll be offset from the end. Let’s see some examples:


Let’s figure out how slicing works in Python.
