Python finds the last occurrence in string | Example code

Use the Python rfind() method to find the last occurrence in the string. This function returns a “-1” if a substring (char) is not found.

string.rfind(value, start, end) 

Note: If the value is not found, the rfind() method returns -1, but the rindex() method will raise an exception:
