python - 如何从字典中删除字典中的重复条目？

Question

我的代码的目标是，我正在解析的文件中不应出现超过一个具有相同姓名和出生日期的人。

这是我在名为 ind 的字典中的字典:

{I19: {'BIRT': '13 FEB 1981', 'sex': 'M', 'id': 'I19', 'family': 'F23', 'name': 'Dick /Smith/'}}
{I32: {'BIRT': '27 MAY 1991', 'sex': 'M', 'id': 'I32', 'family': 'F16', 'name': 'Nick /Tary/'}}
{I30: {'BIRT': '3 SEP 1993', 'sex': 'F', 'id': 'I30', 'family': 'F16', 'name': 'Mary /Test/'}}
{I26: {'BIRT': '2 JUN 1983', 'sex': 'F', 'id': 'I26', 'family': 'F23', 'name': 'Jane /Smith/'}}
{I01: {'name': 'Joe /Smith/', 'family': 'F23', 'BIRT': '15 JUL 1960', 'sex': 'M', 'id': 'I01', 'DEAT': '31 DEC 2013'}}
{I07: {'BIRT': '23 SEP 1960', 'sex': 'F', 'id': 'I07', 'family': 'F23', 'name': 'Jennifer /Smith/'}}
{I19: {'BIRT': '13 FEB 1981', 'sex': 'M', 'id': 'I19', 'family': 'F23', 'name': 'Dick /Smith/'}}

我的代码应该删除 Dick Smith 的一个条目，因为有 2 个条目。

这是我到目前为止这部分的代码(尚未删除重复项):

for individual in ind:
    name1 = ind[individual]['name']
    bdate1 = ind[individual]['BIRT']
    for individual_2 in ind:
        name2 = ind[individual]['name']
        bdate2 = ind[individual]['BIRT']
        if name1 == name2 and bdate1 == bdate2:
            print("{} already exists. Removing duplicate entry.".format(name1))

但这给了我:

Dick /Smith/ already exists. Removing duplicate entry.
Dick /Smith/ already exists. Removing duplicate entry.
Dick /Smith/ already exists. Removing duplicate entry.
Dick /Smith/ already exists. Removing duplicate entry.
Dick /Smith/ already exists. Removing duplicate entry.

如果这个问题看起来很简单，我深表歉意 - 我对此很陌生。将不胜感激任何见解。

list_of_dict = [{'I19': {'BIRT': '13 FEB 1981', 'sex': 'M', 'id': 'I19', 'family': 'F23', 'name': 'Dick /Smith/'}},
     {'I32': {'BIRT': '27 MAY 1991', 'sex': 'M', 'id': 'I32', 'family': 'F16', 'name': 'Nick /Tary/'}}
,{'I30': {'BIRT': '3 SEP 1993', 'sex': 'F', 'id': 'I30', 'family': 'F16', 'name': 'Mary /Test/'}}
,{'I26': {'BIRT': '2 JUN 1983', 'sex': 'F', 'id': 'I26', 'family': 'F23', 'name': 'Jane /Smith/'}}
,{'I01': {'name': 'Joe /Smith/', 'family': 'F23', 'BIRT': '15 JUL 1960', 'sex': 'M', 'id': 'I01', 'DEAT': '31 DEC 2013'}}
,{'I07': {'BIRT': '23 SEP 1960', 'sex': 'F', 'id': 'I07', 'family': 'F23', 'name': 'Jennifer /Smith/'}}
,{'I19': {'BIRT': '13 FEB 1981', 'sex': 'M', 'id': 'I19', 'family': 'F23', 'name': 'Dick /Smith/'}}]

new_d = {v['name'] : {k : v} for d in list_of_dict for k,v in d.items()}

for v in new_d.values():
    print(v)

输出

{'I19': {'BIRT': '13 FEB 1981', 'sex': 'M', 'id': 'I19', 'family': 'F23', 'name': 'Dick /Smith/'}}
{'I32': {'BIRT': '27 MAY 1991', 'sex': 'M', 'id': 'I32', 'family': 'F16', 'name': 'Nick /Tary/'}}
{'I30': {'BIRT': '3 SEP 1993', 'sex': 'F', 'id': 'I30', 'family': 'F16', 'name': 'Mary /Test/'}}
{'I26': {'BIRT': '2 JUN 1983', 'sex': 'F', 'id': 'I26', 'family': 'F23', 'name': 'Jane /Smith/'}}
{'I01': {'name': 'Joe /Smith/', 'family': 'F23', 'BIRT': '15 JUL 1960', 'sex': 'M', 'id': 'I01', 'DEAT': '31 DEC 2013'}}
{'I07': {'BIRT': '23 SEP 1960', 'sex': 'F', 'id': 'I07', 'family': 'F23', 'name': 'Jennifer /Smith/'}}

请注意，在此实现中，仅保存姓氏以防重复
