I want to extract wind
object's data from the following JSON string:
import pandas as pd
from urllib2 import Request, urlopen
import json
from pandas.io.json import json_normalize
request=Request('...')
response_weather = urlopen(request)
w = response_weather.read()
metar = json.loads(w)
wind = pd.DataFrame(json_normalize(metar['wind']))
print wind
KeyError: 'wind'
To get to the wind
object, you first have to get the conditions
object out of metar
. Once you have the conditions
object, you can then pull out the wind
object.
Metar
doesn't have a wind
child, so metar['wind']
doesn't access anything. metar['conditions']
will work, because there is a conditions child
.
Hope that helps!
I want to extract
wind
object's data
Then you want you want metar['conditions']['wind']
And based on your screenshot, that key contains the following object: {direction: 60, directionIsVariable: false, speedKnots: "3.00"}
PS Since that's a single object, I'm not sure what you want to achieve by making it into a pandas.DataFrame
