将元组转换为字典

Question

I've looked all over the internet and consulted a few books but I can't seem to find an example that illustrates what I am trying to do. I loathe to ask this on SO because it feels like a really basic question but I've been banging my head against the wall for the last few hours so here it goes:

How do i turn this:

   item = ((100,May),(160,June),(300,July),(140,August))  

into this:

                {
                item:[
                    {
                        value:100,
                        label:'May'
                    },
                    {
                        value:160,
                        label:'June'
                    },
                    {
                        value:300,
                        label:'July'
                    },
                    {
                        value:140,
                        label:'August'
                    }
                ]
                }

Answer 1

{'item': [dict(value=value, label=label) for value, label in item]}

Answer 2

>>> item = ((100,'May'),(160,'June'),(300,'July'),(140,'August'))
>>> keys = ('value','label')
>>> dd = {'item' : [dict(zip(keys,pair)) for pair in item]}
>>>
>>> import pprint
>>> pprint.pprint(dd)
{'item': [{'label': 'May', 'value': 100},
          {'label': 'June', 'value': 160},
          {'label': 'July', 'value': 300},
          {'label': 'August', 'value': 140}]}

Answer 3

dict(item=map(lambda x: dict(value=x[0],label=x[1]),item))
