i have this above json file .
which holds multiple data set this is just an example with 5 .
i want to pull the status value from the above json .
We can usual do it by result['statushistory'][0]['status']
But it pulls only the 5 values . It is returning only the first value of
the last statushistory .
How can i write a code which returns all the value of statushistory ?
And also if the statushistory doesnt have any status how can i mange that in the code ?(i.e return status only if statushistory has status present in it)

Answer 1

Something like:
statushistory_list = [result["statushistory"] for result in json_data["result"]]
status_list = [
[item["status"] for item in statushistory if "status" in item]
for statushistory in statushistory_list
]
this will get you:
[['DOWN'], ['UP'], ['UP'], ['UP'], ['UP', 'DOWN', 'UP']]
If it's not what you are looking for then, please show an example of the output you would like.
