2 Usage

1. Prepare station.csv.

   Note

   station.csv (you can find it from the https://e-service.cwb.gov.tw/wdps/obs/state.htm)

2. run the function of collect_weather_tw you will see the result!

   def collect_weather_tw(station_csv_path: Path, output_path,
                          end_date: datetime.date, begin_date: datetime.date,
                          query_format,
                          convert2num):

You can refer to __init__.py for more help

1. Prepare config.yaml and use this path as input parameter

2. run __init__.py
