Python inline list formatting

A question on the StackOverflow:

Put the following format:

[{"id": 1, "title": "Node1", "parent": "NULL"},{"id": 2, "title": "Node2", "Parent": 1},{"id": 3,     "title": "Node3", "Parent": 1},{"id": 4, "title": "Node4", "Parent": 2},{"id": 5, "title": "Node5", "Parent": 2}]

Change to:

    [{       ' id ':1,       ' Title ': ' Node1 ',         ' Childs ':[            {                ' id ':2,             ' title ': ' Node2 '               ' Childs ':[                  {                      ' id ':4,                    ' title ': ' Node4 ',                    ' Childs ':  []  &NBsp;            },                {                      ' id ':5,                    ' title ': ' Node5 ',                    ' Childs ':  []               }             ]          },         {                ' id ':3,              ' title ': ' Node3 ' &NBsp;            ' Childs ':[]          }      ]   }]

Related code: (mainly using the variability of Python objects, such as dict,list are variable.) so that the depth of the data can be simplified)

result, t = [], {}for i in K: # K for the above data, K recommended to sort by parent i[' childs ' = [] if i[' parent '] = = ' null ': Del i[' parent '] result.append (i) t[1] = Result[0] else:t[i[' parent ']][' Childs '].append (i) t[i [' ID ']] = t[i[' parent ']][' Childs '][-1] del t[i[' parent ']][' Childs '][-1][' parent ']print result

Results:

z:\download>k.py[{' Childs ': [{' Childs ': [{' Childs ': [], ' ID ': 4, ' title ': ' Node4 '}, {' Childs ': [], ' ID ': 5, ' title ': ' N ' Ode5 '}], ' ID ': 2, ' title ': ' Node2 '}, {' Childs ': [], ' ID ': 3, ' title ': ' Node3 '}], ' ID ': 1, ' title ': ' Node1 '}]
