Question

我有一个像这样的字典的python列表：

[{'George': {u'finance': {u'investing': {u'venture capital': 'Peter'}}}},
 {'George': {u'finance': {u'investing': {u'venture capital': 'John'}}}},
 {'George': {u'finance': {u'investing': {u'venture capital': 'Kate'}}}}]

我想分组，所以最后的结果将是：

{'George': {u'finance': {u'investing': {u'venture capital': ['Peter','John','Kate'}}}}

如何将此词典列表分组？

到目前为止你尝试了什么？

如果你的数据结构如上例所示得到修复，你可以尝试这样的事情：

merged_dict = {}
for d in your_list_of_dicts:
    for k in d:
        if k not in merged_dict.keys():
            merged_dict[k] = d[k]
            merged_dict[k]['finance']['investing']['venture capital'] = [merged_dict[k]['finance']['investing']['venture capital']]
        else:
            merged_dict[k]['finance']['investing']['venture capital'].append(d[k]['finance']['investing']['venture capital'])
