- add_processor(fieldname: str, func_: Union[List[Callable[[str], Any]], Callable[[str], Any]], handle: Optional[str] = None) None
Add a processor to process fields in a row.
- Parameters
fieldname (required) – Name of the field upon which the processor should be executed.
func (required) – Field processor function reference or a list of such function references. All function references added with the same handle will be executed for the field, to transform its value in the same order as they are added.
handle (optional) – Processor reference handle to which the processor will be added. If not provided, the handle of the current object will be used.
- Returns
None

- process_row(row: Dict[str, Any], processor_handle: Optional[Union[Type[csvio.processors.processor_base.ProcessorBase], str]] = None) Dict[str, Any]
Process a single row
- Parameters
row (required) – A single dictionary of
fieldname->valuepairs representing a single rowprocessor_handle (optional) – A processor handle or an object that references the processor functions to apply and transform the row values. The processor functions of the current object are used if this argument is not provided.
- Returns
A dictionary representing a processed CSV row
- process_rows(rows: List[Dict[str, Any]], processor_handle: Optional[str] = None) List[Dict[str, Any]]
Process a list of rows
- Parameters
row (required) – A list of dictionaries of
fieldname->valuepairs representing a list of rowsprocessor_handle (optional) – A processor handle or an object that references the processor functions to apply and transform the row values. The processor functions of the current object are used if this argument is not provided.
- Returns
A list of dictionaries representing processed CSV rows
