How to parse geojson files with python?-CodePudding

I added .geojson files that I try to parse, but when I run the code it gives an error like; KeyError: 'area', I know its means but my question is how can I achieve the keys inside raw_airport.loc

import geopandas as gpd
raw_airport = gpd.read_file('./taxiways-and-runways.geojson')

runway_paths = (
    raw_airport.loc[lambda x: x['area'] != 'yes']
               .loc[lambda x: x['aeroway'] == 'runway']
)

taxiway_paths = (
    raw_airport.loc[lambda x: x['area'] != 'yes']
               .loc[lambda x: x['aeroway'] == 'taxiway']
               .loc[:, ['geometry']]
)

raw_stands = gpd.read_file('./gates-and-ramps.geojson')

stands = raw_stands.dropna(subset=['ref'])

After running, at the right side you will see the "Variable Explorer" you can see the details on there.

Yor problem is probably that keys are sometimes missing, causing expressions like x['area'] to throw a KeyError. If you use the .get method (i.e, x.get('area') instead, you get None (or a default value of your choice) when the key is missing.
