Lesson 2

Ready for review (I hope)!  Time consuming, but fun and interesting!  Fingers crossed everything is correct!
Also, instead of `print` here, why not capture that? If `FISHY.index(OLD)` tells you where this string starts, couldn't you use that instead of hard-coding `18` and `27` below? Similarly, if you know the length of `OLD` that + your new index value equal the start of the old string.

In general, we like to avoid hard-coding which is putting in direct numbers as below. You should be able to complete this without typing a single number.
