Here you need:

if prefixes == "O" or prefixes ==  "Q"

It's not because "O and Q are present in the entire string" - it's
because your expression

prefixes == "O" or "Q"

evaluates as

(prefixes == "O") or ("Q")

Since a string containing a value always evaluates as true, your
expression was always true, too.
