access to nested data

I need to access structured data in a nested way but I didn't understand how to do it.

The data is structured in this way:

{'function':'data_chip',
 'group_id': 172,
 'Types': [
    {'TMS0202':'SR-20',
     'TMS0207':'SR-22',
     'TMS0201': 'TI-4000',
     'TMS0203': 'TI-450'
    }
 ]
}

to access nested data you could using data['keyword'] or data.get('keyword', default value)

In your case that you want information on types (I assumed you want all data) you could looping on types, using something like:

datas = {'function':'data_chip',
 'group_id': 172,
 'Types': [
    {'TMS0202':'SR-20',
     'TMS0207':'SR-22',
     'TMS0201': 'TI-4000',
     'TMS0203': 'TI-450'
    }
 ]
}

for data in datas['types']:

Is there a particular part you're trying to access?

Here are a few examples:

$ python
Python 3.7.2 (default, Dec 27 2018, 07:35:06) 
[Clang 10.0.0 (clang-1000.11.45.5)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> data = {'function':'data_chip',
...  'group_id': 172,
...  'Types': [
...     {'TMS0202':'SR-20',
...      'TMS0207':'SR-22',
...      'TMS0201': 'TI-4000',
...      'TMS0203': 'TI-450'
...     }
...  ]
... }
>>> data['function']
'data_chip'
>>> data['Types'][0]['TMS0202']
'SR-20'
>>> data['group_id']
172

To access the top-level data, use a single dictionary index:

data['function'] —> 'data chip'

To access the data in the Types key, you need to access the list first then the dictionary inside it:

data['Types'][0]['TMS0202'] —> 'SR-20'

Each time you get a level deeper, consider what data type you now need to access. If it is a dict you need the keys, if it is a list you need the integer index. Each level you access is another retrieval using square brackets:

data[key][index][key]
