• "rfind" is taking three inputs: what you are looking for, where to begin the search, and where to end the search. Although rfind searches from the end to the beginning, when you put in the begin and end points, they need to be in sequential order (yes, it is confusing).
• "find" is taking two inputs: what you are looking for, and where to begin looking. "find" will give you the first location that the thing you want appears at.

• The first line defines "final" as the index number where the string ends - the index number of "z".
• The second line searches through the alphabet from the index number 0 ("a") to the index number of 'final' ("z", at index number 26). The search is for the letter "f" - but it begins at "z" and then works towards "a" because it is an rfind. You name the index number of the first "f" that the search finds to be "startpoint".
• The third line searches through the alphabet looking for "j". The search begins at index number 0 ("a"). When it finds the "j", you name the location index number "endpoint".
• The last line then prints the section of the alphabet that falls between the index numbers "startpoint"+1 and "endpoint". You must add one to the "startpoint" because you found the index number of "f", so one after that is where you want to begin - at "g". Since range is up to but not including, although you found the index of "j", no "j" will be printed. It'll only print just the letters with the index numbers after "f" and before "j" -> "ghi".
