特定仪表板的Python格式

Question

我在列表中获取输出

[
(u'Shift 1', u'NURSES', u'ANITHA M.N.', u'A'), 
(u'Shift 1', u'Counsellors', u'SUSHMITHA B.', u'A'), 
(u'Shift 2', u'Counsellors', u'ALEX THOMAS MATHEW', u'B')
] 

我想将输出格式化如下。

{
    name: "Shift 1",
    id: "A",
    expanded: true,
    children: [{
            name: "Counsellors",
            id: "A.1",
            children: [{
                name: "SUSHMITHA B.",
                id: "A.1.1"
            }, ]
        }, {
            name: "Nurses",
            id: "A.2",
            children: [{
                name: "ANITHA M.N",
                id: "A.2.1"
            }, ]

        },

    ]
}, {
    name: "Shift 2",
    id: "B",
    expanded: true,
    children: [{
            name: "Counsellors",
            id: "B.1",
            children: [{
                name: "ALEX THOMAS MATHEW",
                id: "B.1.1"
            }, ]
        },

    ]
},

必须完成以下格式。 在python中使用了元组列表中的多个组的概念。

from itertools
import groupby
import pdb

L = [(u 'Shift 1', u 'NURSES', u 'ANITHA. BHARATHAN', u 'A'), (u 'Shift 1', u 'NURSES', u 'ANITHA M.N.', u 'A'), (u 'Shift 1', u 'Counsellors', u 'SUSHMITHA B.', u 'A'), (u 'Shift 2', u 'Counsellors', u 'ALEX THOMAS MATHEW', u 'B')]
for x, y in groupby(sorted(L), lambda t: t[0]):
    children = []
    for c, d in groupby(sorted(y), lambda t: t[1]):
        children.append('children: {}: {}'.format(c, ', '.join(c[2]
            for c in d)))

无法获得上述格式，但接近它。任何帮助将不胜感激。
