I wrote the below code

    def wrapper(function):
        def wrapped(*args, **kwargs):
            if (salt.utils.path.which_bin(exes) is None):
                raise CommandNotFoundError('None    of    provided    binaries({0})    was    not    found    in    $PATH.'.format(["'{0}'".format(exe) for exe in exes]))
            return function(*args, **kwargs)
        return identical_signature_wrapper(function, wrapped)
    return wrapper

What's a good function header?

Here's a good function header?
