hope this fix your issue The easy way is to get rid of the * in your default rule at the end and just use
code :
.    { append_to_buffer(*yytext); }

I wish this helpful for you Quoting from Lexical Translations:
code :
x=a+++b
x=(a++)+b

I wish did fix the issue. I've decided that maximal munch is the Right Thing. Given "1.23" a parser that returns 1 is just wrong. I've been tripped up by this myself because I once tried to write a "maybeRead" looking like this:
code :
maybeRead :: (Read a) => String -> Maybe a
maybeRead str = case reads str of
   [v, ""] -> Just v
   _ => Nothing
expPart <- optional "" $ do {...}
 myOpt d p = p <++ return d
Does PLY's lexer support "maximal munch"?

hope this fix your issue PLY uses Python's own re package to match tokens, by building a single regular expression as a combination of alternatives. Since python's regular expression library is not maximal munch, neither is PLY.
Instead, the match selected is the first pattern in this big regular expression which matches, and the order is documented in the PLY nanual:

I wish this helpful for you As my comment suggests, I don't really think there is something to improve.
However, performance-wise, you could use filter to push the loop down to C level which may be beneficial if there are a lot of stacks.
code :
def __find_stack(self, connection, stack_info):
    stacks = connection.list_stacks()
    return list(filter(lambda stack: stack_info in stack.values(), stacks))

wish helps you The maximal munch algorithm is implemented by adding a small amount of mutable state to the DFA executor, and adding the ability of the DFA executor to "rewind" the input: in effect, providing it with functions like tell() and seek().
It's also worth noting that the DFA is not complete, in the sense that the transition function is not complete. Some {state, input} pairs do not have a defined result. [Note 2]
