如何将列表（大小为一）转换为字典？

Question

I have a list of dictionaries, and within the dictionaries there are dictionaries, and within those dictionaries, there are lists as values - within those lists is the information I need to access.

I want to turn the lists into dictionaries. The entire list of dictionaries are set up like this:

data = [{'date': 'Aug 1 1980', 
       'hour': '2PM', 
       'group': {'location' : 
                  [{'country': 'United States', 
                  'state': 'Utah', 
                  'city': 'St. George', 
                  'coordinates': [37.0965, 113.5684]}]},
        {'date': 'Aug 1 1980', 
        'hour': '4PM', 
        'group': {'location' : 
                   [{'country': 'United States', 
                   'state': 'Utah', 
                   'city': 'St. George', 
                   'coordinates': [37.0965, 113.5684]}]}]

I need the the coordinates but the type of location is a list. How can I turn this list into a dictionary? Should I start by splitting by ':' and ','s into keys and values? That seems like an awful way to do it and I'm hoping someone can help me with a better, quicker way.

Edit I would want my dictionary to look like this:

{'country': 'United States', 'state': 'Utah', 'city' :'St George', 'coordinates': [37.0965, 113.5684]}

I think the following does what you want (although I'm not totally sure since I had to fix your input data to make it valid and guess a little on what exactly you wanted the result to be.

from pprint import pprint

data = [{'date': 'Aug 1 1980',
         'hour': '2PM',
         'group': {'location': [{'country': 'United States',
                                 'state': 'Utah',
                                 'city': 'St. George',
                                 'coordinates': [37.0965, 113.5684]}]}},
        {'date': 'Aug 1 1980',
         'hour': '4PM',
         'group': {'location': [{'country': 'United States',
                                 'state': 'Utah',
                                 'city': 'St. George',
                                 'coordinates': [37.0965, 113.5684]}]}}]

fixed_data = []
for dct in data:
    dct['group']['location'] = dct['group']['location'][0]
    fixed_data.append(dct)

pprint(fixed_data, sort_dicts=0)

Printed result:

[{'date': 'Aug 1 1980',
  'hour': '2PM',
  'group': {'location': {'country': 'United States',
                         'state': 'Utah',
                         'city': 'St. George',
                         'coordinates': [37.0965, 113.5684]}}},
 {'date': 'Aug 1 1980',
  'hour': '4PM',
  'group': {'location': {'country': 'United States',
                         'state': 'Utah',
                         'city': 'St. George',
                         'coordinates': [37.0965, 113.5684]}}}]
