我如何创建此词典列表

Question

我有一份字典

[{'name_field': u'casino_logo', 'contentid_id': 15L, 'value': u'assets/images/crown.png', 'title': u'Royal casino casino4'}, {'name_field': u'casino_logo', 'contentid_id': 16L, 'value': u'assets/images/crown.png', 'title': u'Royal casino casino1'}, {'name_field': u'casino_logo', 'contentid_id': 17L, 'value': u'assets/images/crown.png', 'title': u'Royal casino casino3'}, {'name_field': u'casino_logo', 'contentid_id': 18L, 'value': u'assets/images/crown.png', 'title': u'Royal casino casino2'}, {'name_field': u'raiting_casino', 'contentid_id': 15L, 'value': u'9.9', 'title': u'Royal casino casino4'}, {'name_field': u'raiting_casino', 'contentid_id': 16L, 'value': u'9', 'title': u'Royal casino casino1'}, {'name_field': u'raiting_casino', 'contentid_id': 17L, 'value': u'8.2', 'title': u'Royal casino casino3'}, {'name_field': u'raiting_casino', 'contentid_id': 18L, 'value': u'9.3', 'title': u'Royal casino casino2'}, {'name_field': u'bonus_code', 'contentid_id': 15L, 'value': u'AX777', 'title': u'Royal casino casino4'}, {'name_field': u'bonus_code', 'contentid_id': 16L, 'value': u'AX7772', 'title': u'Royal casino casino1'}, {'name_field': u'bonus_code', 'contentid_id': 17L, 'value': u'AX777', 'title': u'Royal casino casino3'}, {'name_field': u'bonus_code', 'contentid_id': 18L, 'value': u'AX7772', 'title': u'Royal casino casino2'}, {'name_field': u'bonus_summa', 'contentid_id': 15L, 'value': u'200', 'title': u'Royal casino casino4'}, {'name_field': u'bonus_summa', 'contentid_id': 16L, 'value': u'200', 'title': u'Royal casino casino1'}, {'name_field': u'bonus_summa', 'contentid_id': 17L, 'value': u'200', 'title': u'Royal casino casino3'}, {'name_field': u'bonus_summa', 'contentid_id': 18L, 'value': u'200', 'title': u'Royal casino casino2'}, {'name_field': u'bonus_min_depozit', 'contentid_id': 15L, 'value': u'1000000', 'title': u'Royal casino casino4'}, {'name_field': u'bonus_min_depozit', 'contentid_id': 16L, 'value': u'1000000', 'title': u'Royal casino casino1'}, {'name_field': u'bonus_min_depozit', 'contentid_id': 17L, 'value': u'1000000', 'title': u'Royal casino casino3'}, {'name_field': u'bonus_min_depozit', 'contentid_id': 18L, 'value': u'1000000', 'title': u'Royal casino casino2'}, '...(remaining elements truncated)...']

我如何获得结构

{casinos:[{'id':16,'title':Royal casino casino3,'fields':[{'name_feild':'bonus_min_depozit','value':'10',...}],...}]}

我试过了：

for item in casinos:  
    info_casino[item['contentid_id']].append({'name_field':item['name_field'],'value':item['value']}) 
    casino[item['contentid_id']] = {'fields':info_casino[item['contentid_id']],'title':item['title']}

但这没用。

Answer 1

您可以使用“字典理解”来实现此目的：

my_dict = {item['name_field']: item for item in my_list}

其中my_list是问题中提到的dict列表。

如果您要删除结果字典的'name_field'值，则可以将新dict创建为：

my_dict = {}
for item in my_list:
    my_dict[item['name_field']] = item
    del item['name_field']
