从字典列表中删除重复项 [英] Remove duplicates from list of dicts

问题描述

如果嵌套字典前面没有键，我现在可以删除重复项。我可以使用此功能的字典列表的一个示例是：

I presently have the ability to remove duplicates if there is no key in front of the nested dictionary. An example of my list of dicts that works with this function is:

 [{'asndb_prefix': '164.39.xxx.0/17',
  'cidr': '164.39.xxx.0/17',
  'cymru_asn': 'XXX',
  'cymru_country': 'GB',
  'cymru_owner': 'XXX , GB',
  'cymru_prefix': '164.39.xxx.0/17',
  'ips': ['164.39.xxx.xxx'],
  'network_id': '164.39.xxx.xxx/24',},
 {'asndb_prefix': '54.192.xxx.xxx/16',
  'cidr': '54.192.0.0/16',
  'cymru_asn': '16509',
  'cymru_country': 'US',
  'cymru_owner': 'AMAZON-02 - Amazon.com, Inc., US',
  'cymru_prefix': '54.192.144.0/22',
  'ips': ['54.192.xxx.xxx', '54.192.xxx.xxx'],
  'network_id': '54.192.xxx.xxx/24',
  }]

def remove_dict_duplicates(list_of_dicts):
    """
    "" Remove duplicates in dict 
    """
    list_of_dicts = [dict(t) for t in set([tuple(d.items()) for d in list_of_dicts])]
    # remove the {} before and after - not sure why these are placed as 
    # the first and last element 
    return list_of_dicts[1:-1]

但是，我希望能够根据键和该词典中关联的所有值删除重复项。因此，如果内部有相同的键，但值不同，则我不想将其删除，但是如果有完整的副本，则将其删除。

However, I would like to be able to remove duplicates based on the key and all values associated within that dictionary. So if there the same key with different values inside I would like to not remove it, but if there is a complete copy then remove it.

    [{'50.16.xxx.0/24': {'asndb_prefix': '50.16.0.0/16',
   'cidr': '50.16.0.0/14',
   'cymru_asn': 'xxxx',
   'cymru_country': 'US',
   'cymru_owner': 'AMAZON-AES - Amazon.com, Inc., US',
   'cymru_prefix': '50.16.0.0/16',
   'ip': '50.16.221.xxx',
   'network_id': '50.16.xxx.0/24',
   'pyasn_asn': xxxx,
   'whois_asn': 'xxxx'}},
   // This would be removed
   {'50.16.xxx.0/24': {'asndb_prefix': '50.16.0.0/16',
   'cidr': '50.16.0.0/14',
   'cymru_asn': 'xxxxx',
   'cymru_country': 'US',
   'cymru_owner': 'AMAZON-AES - Amazon.com, Inc., US',
   'cymru_prefix': '50.16.0.0/16',
   'ip': '50.16.221.xxx',
   'network_id': '50.16.xxx.0/24',
   'pyasn_asn': xxxx,
   'whois_asn': 'xxxx'}},
   // This would NOT be removed
   {'50.16.xxx.0/24': {'asndb_prefix': '50.999.0.0/16',
   'cidr': '50.999.0.0/14',
   'cymru_asn': 'xxxx',
   'cymru_country': 'US',
   'cymru_owner': 'AMAZON-AES - Amazon.com, Inc., US',
   'cymru_prefix': '50.16.0.0/16',
   'ip': '50.16.221.xxx',
   'network_id': '50.16.xxx.0/24',
   'pyasn_asn': xxxx,
   'whois_asn': 'xxxx'}}]

我该怎么做？谢谢。

推荐答案

要从字典列表中删除重复项：

To remove duplicates from a list of dicts:

list_of_unique_dicts = []
for dict_ in list_of_dicts:
    if dict_ not in list_of_unique_dicts:
        list_of_unique_dicts.append(dict_)
