Keep certain Values from JSON obj, deeper in their structure-CodePudding

I am using Python in AWS services.

I have this large JSON object:

I have already isolated the detected text info:

for item in response['TextDetections']:
print(text['DetectedText'])

and I can also go further by assigning the other objects of the main item:

text = item['DetectedText']
type = item['Type']
conf = item['Confidence']

etc.

My question is: how do I isolate the item within the item within, i.e. in deeper levels? To be more specific, I would like to do something like:

left = item["DetectedText":{"Geometry":{"BoundingBox":{"Left"}}}]

this does not seem to work, no matter in how many ways I tried to syntax it.

CodePudding user response：

It should be:

for item in response['TextDetections']:
    left = item['Geometry']['BoundingBox']['Left']
    print(left)
