How to read dynamic/changing keys from JSON in Python - json

Question

I am using the UK Bus API to collect bus arrival times etc.
In Python 3 I have been using....
try:
connection = http.client.HTTPSConnection("transportapi.com")
connection.request("GET", "/v3/uk/bus/stop/xxxxxxxxx/live.json?app_id=xxxxxxxxxxxxxxx&app_key=xxxxxxxxxxxxxxxxxxxxxxxxxxx&group=route&nextbuses=yes")
res = connection.getresponse()
data = res.read()
connection.close()
from types import SimpleNamespace as Namespace
x = json.loads(data, object_hook=lambda d: Namespace(**d))
print("Stop Name : " + x.stop_name)
Which is all reasonably simple, however the JSON data returned looks like this...
{
"atcocode":"xxxxxxxx",
"smscode":"xxxxxxxx",
"request_time":"2020-03-10T15:42:22+00:00",
"name":"Hospital",
"stop_name":"Hospital",
"bearing":"SE",
"indicator":"adj",
"locality":"Here",
"location":{
"type":"Point",
"coordinates":[
-1.xxxxx,
50.xxxxx
]
},
"departures":{
"8":[
{
"mode":"bus",
"line":"8",
"line_name":"8",
"direction":"North",
"operator":"CBLE",
"date":"2020-03-10",
Under "departures" the key name changes due to the bus number / code.
Using Python 3 how do I extract the key name and all subsequent values below/within it?
Many thanks for any help!

Answer 1

You can do this:
for k,v in x["departures"].items():
print(k,v) #or whatever else you wanted to do.
Which returns:
8 [{'mode': 'bus', 'line': '8', 'line_name': '8', 'direction': 'North', 'operator': 'CBLE', 'date': '2020-03-10'}]
So k is equal to 8 and v is the value.
