How can I select deeply nested key:values from dictionary in python

Question

I have downloaded a json data from a website, and I want to select specific key:values from a nested json. I converted the json to python dictionary. Then I used dictionary

I suggest you to use python-benedict, a solid python dict subclass with full keypath support and many utility methods.

It provides IO support with many formats, including json.

You can initialize it directly from the json file:

from benedict import benedict

d = benedict.from_json('data.json')

Now your dict has keypath support:

print(d['payload.metadata.coverImage.id'])

# or use get to avoid a possible KeyError
print(d.get('payload.metadata.coverImage.id'))

Installation: pip install python-benedict
