[Tutor] trouble with function-- trying to check

[Isaac]

a, b, c, or d is a type('str') not boolean which is what (c in "crab") is.
The [in] operator takes presedence, the first 3 times (c in "crab") returns
true and the last returns false; but the strings a, b, c, or d do not ==
true or false - therefore the test (c == (c in "crab")) always returns
false.


(I think)
