How to extract the value from a nested dictionary within a nested list in python

Question

The following is my code snippet. I am trying to extract the value of 'string' and 'score' from a nested dictionary within a nested list . How do I accomplish this?

Expected output would be 'Object element' and '1.0'

[{'Form': [{'string': 'object element', 'score': 1.0,}],
  'types': ['http://google.com'],
'threshold':34}]

What have you tried? Do you want this done in a loop, or simply extract the value of the first(only) 'string' and 'score' values? Also, I think the final braces might be a bit mixed up? — M.T

I tried to flatten the list first through reduce function and then tried to unpack the value via list indexing, but no luck.. Yes, I want this to be done in a loop. — venkatttaknev

This should work

data = [{'Form': [{'string': 'object element', 'score': 1.0,}], 'types': ['http://google.com'], 'threshold':34},{'Form': [{'string': 'data store', 'score': 0.9,}], 'types': ['http://google.com'], 'threshold':23}]

for d in data:
    print(d['Form'][0]['string'])
    print(d['Form'][0]['score'])

Thanks @Nithin. Actually I missed stating my problem clearly. I would ideally like the solution in loop cos my code is of below format

[{'Form': [{'string': 'object element', 'score': 1.0,}],   'types': ['http://google.com'], 'threshold':34},{'Form': [{'string': 'data store', 'score': 0.9,}],   'types': ['http://google.com'], 'threshold':23}]
