Parsing Api With Python - How To Handle Json With Bom

I'm using Python 2.7.11 on windows to get JSON data from API (data on trees in Warsaw, Poland, but nevermind that). I want to generate output csv file with all the data provided by

Solution 1:

You need to put the key with the unicode character:

To know how to do it, one easy way is to print the keys:

>>> import requests
>>> res = requests.get('https://api.um.warszawa.pl/api/action/datastore_search/?resource_id=ed6217dd-c8d0-4f7b-8bed-3b7eb81a95ba')
>>> data = res.json()
>>> records = data['result']['records']
>>> records[0]
{u'numer_adres': u'', u'stan_zdrowia': u'dobry', u'y_wgs84': u'52.21865', u'y_pl2000': u'5787241.04475524', u'adres': u'ul. ALPEJSKA', u'x_pl2000': u'7511793.96937063', u'lokalizacja': u'Ulica ALPEJSKA', u'wiek_w_dni': u'60', u'miasto': u'Warszawa', u'jednostka': u'Dzielnica Wawer', u'pnie_obwod': u'73', u'wysokosc': u'14', u'data_wyk_pom': u'20130709', u'dzielnica': u'Wawer', u'\ufeffx_wgs84': u'21.172584', u'numer_inw': u'D386200', u'_id': 125435, u'gatunek_1': u'Quercus robur', u'gatunek': u'd\u0105b szypu\u0142kowy', u'srednica_k': u'7'}
>>> records[0].keys()
[u'numer_adres', u'stan_zdrowia', u'y_wgs84', u'y_pl2000', u'adres', u'x_pl2000', u'lokalizacja', u'wiek_w_dni', u'miasto', u'jednostka', u'pnie_obwod', u'wysokosc', u'data_wyk_pom', u'dzielnica', u'\ufeffx_wgs84', u'numer_inw', u'_id', u'gatunek_1', u'gatunek', u'srednica_k']
>>> records[0][u'\ufeffx_wgs84']
u'21.172584'

As you can see, to get your key, you need to write it as '\ufeffx_wgs84' with the unicode character that is causing trouble.

Note: I don't know if you are using python2 or 3, but you might need to put a u before your string declaration in python2 to declare it as unicode string.
