If step isn't explicitly given, the default value is 1. I am a Jedi, like my father before me. There are a couple of ways to slice a list, most common of which is by using the : operator with the following syntax: alist start:end alist start:end:step The start parameter represents the starting index, end is the ending index, and step is the number of items that are 'stepped' over. ![]() This works by looping through a string and assigning its values in reverse order to another string. With two strings as operands, this operator returns. def reversestring (string): length len (string) temp '' for i in range (length): temp + string length - i - 1 return temp print (reversestring ('foo')) prints 'oof'. String splicing or indexing is a method by which we can access any character or group of characters from a python string. This makes the step go backwards, including each element it steps on, resulting in the string being printed back in reverse: string 'I’ll never turn to the dark side. The first technique youll use to reverse a string involves a for loop and the concatenation operator ( + ). 1 I understand how to normally slice a string and reverse it, but dont get how to do both simultaneously.

Create a slice that starts at the end of the string, and moves backwards. To reverse a string, we can set the step of the slice notation to -1.
