import json

with open('data.txt') as json_file:
    data = json.load(json_file)
    print(data['actual']['stationmeasurements'][0])

For first set of curlies (idx = 0) it prints:

{'$id': '4', 'stationid': 6391, 'stationname': 'Meetstation Arcen', 'lat': 51.5, 'lon': 6.2, 'regio': 'Venlo', 'timestamp': '2019-10-21T14:30:00', 'weatherdescription': 'Zwaar bewolkt', 'iconurl': 'https://www.buienradar.nl/resources/images/icons/weather/30x30/c.png', 'graphUrl': 'https://www.buienradar.nl/nederland/weerbericht/weergrafieken/c', 'winddirection': 'ZW', 'temperature': 14.4, 'groundtemperature': 14.4, 'feeltemperature': 13.5, 'windgusts': 7.6, 'windspeed': 3.8, 'windspeedBft': 3, 'humidity': 72.0, 'precipitation': 0.0, 'sunpower': 100.0, 'rainFallLast24Hour': 3.2, 'rainFallLastHour': 0.0, 'winddirectiondegrees': 214}

JSON files can be loaded as python dictionaries. So basically, what you want is to load the JSON as a dict object and print a given field of said object

import json
x :str = "{ 'key1': 'value1', 'key2': { 'subkey1': 'subval'} }"
dict_object = json.loads(x)
print(x['key2']) # Prints the dict {subkey1: subval}
print(x['key2']['subkey1']) # prints subval
