.. function:: fields(source_df: pd.DataFrame, target_df: pd.DataFrame, names: List[str], normalize: bool = False, err_thr: float = 0.25) -> Result

   Finds fields values difference between dataframes.

   :param names - a list of field names:
   :param normalize - if set, all fields converted to str and processed with lower:
   :type normalize - if set, all fields converted to str and processed with lower: ) and strip(
   :param err_thr - sets the failure threshold for missing values:

   :returns: Result with same, missing and new values.


.. function:: tagged_fields(source_df: pd.DataFrame, target_df: pd.DataFrame, tagged_fields: TaggedFields, tags: List[str]) -> Result

   Compare fields tagged with `tags` between two dataframes.
