in the tuple example. i understand when you say that exactly and the uppercase does not match however the keyword for the search was "tuple" (which it found one instance, so does python recognize plurals?

Sometimes the forms of a word are only different by the addition of one letter (usually "s"), so a string search for the singular form will find it inside the plural, but this is entirely due to character matching individually.

1,641 PointsI had the same question, so I played around with the code. It finds characters inside the string as long as the case is the same. So for instance, you could search for 'mut' and it will find it inside immutable. However, if you searched for 'Mut' it would not work. So it's not that python understands the plurality of 'tuples,' it's just finding 'tuple' inside 'tuples.'

Python Development Techdegree Graduate 12,788 Pointsthere are some third party modules that will allow for pluralization of words as in the following link https://www.geeksforgeeks.org/python-program-to-convert-singular-to-plural/
so if you could make it plural, I believe you could use that same logic to reverse the search
