Reverse string using slicing The first and easiest way to reverse a string in python is to use slicing. We can create a slice of any string by using the syntaxstring_name[ start : end : interval ]where start and
The easiest and fastest way to reverse a string in Python is to use the slice operator [start:stop:step]. When you pass a step of -1 and omit the start and end values, the slice operator reverses the string. A more verbose, but readable (and slower) version of the string reversal ...
When constructing a slice, as in[6:11], the first index number is where the slice starts (inclusive), and the second index number is where the slice ends (exclusive), which is why in our example above the range has to be the index number that would occur after the string ends. When...
