        return len(self.hospitals)

Expected Result:

    def n_hospitals(self):
        """
        [summary]

        Returns:
            int: [description]
        """
        return len(self.hospitals)

    def n_hospitals(self):
        """

        Returns:
            [type]: [description]
        """
