A pathlib.Path class for dapla

Project description

dapla-path

pathlib.Path for dapla

Opprettet av: ort ort@ssb.no


Path (dapla)

import dapla as dp
import pandas as pd

from daplapath.path import Path
folder = Path('ssb-kart-data-delt-prod/analyse_data/klargjorte-data/2024')
folder
'ssb-kart-data-delt-prod/analyse_data/klargjorte-data/2024'

Fungerer som tekst

folder.startswith("ssb")
True
dp.FileClient.get_gcs_file_system().exists(folder)
True

Med metoder og attributter ala pathlib.Path

folder.exists()
True
folder.is_dir()
True
file = folder / "ABAS_kommune_utenhav_p2024_v1.parquet"
file
'ssb-kart-data-delt-prod/analyse_data/klargjorte-data/2024/ABAS_kommune_utenhav_p2024_v1.parquet'
file.parent
'ssb-kart-data-delt-prod/analyse_data/klargjorte-data/2024'

Og noen pandas attributter

Uten å lese filen

       'SHAPE_Area', 'geometry'],
      dtype='object')
