Python string rfind() is an inbuilt handling method that returns the highest index of the substring that is passed in the rfind() function as an argument. If that substring is not present in the main string, the method returns -1. There are three arguments passed, first is the substring, starting and ending indexes of the main string in which we want to search. To give starting and ending indexes is optional, and if we don’t give it, 0 and length of string -1 is taken as default.
Python rfind() method finds a substring in the string and returns the highest index. It means it returns the index of the most rightmost matched substring of the string. It returns -1 if substring not found.
