(self, path, base=None, index=None, create=False)
return os.path.exists(path)
Add a new path to the list of search paths. Return False if the
            path does not exist.

            :param path: The new search path. Relative paths are turned into
                an absolute and normalized form. If the path looks like a file
                (not ending in `/`), the filename is stripped off.
            :param base: Path used to absolutize relative search paths.
                Defaults to :attr:`base` which defaults to ``os.getcwd()``.
            :param index: Position within the list of search paths. Defaults
                to last index (appends to the list).

            The `base` parameter makes it easy to reference files installed
            along with a python module or package::
