How to remove the same pair with diffrent order in values inside dictionary python?-CodePudding

I have a list of dictionary that look like that

 {'ip_src': '2.2.2.2',
  'ip_dst': '1.1.1.1',
  'src_id': 43,
  'src_name': 'test1',
  'dst_id': 48,
  'dst_name': 'test2'},

 {'ip_src': '1.1.1.1',
  'ip_dst': '2.2.2.2',
  'src': 48,
  'src_name': 'test2',
  'dst': 43,
  'dst_name': 'test1'},


 {'ip_src': '4.4.4.4',
  'ip_dst': '3.3.3.3',
  'src_id': 41,
  'src_name': 'test1',
  'dst_id': 47,
  'dst_name': 'test2'},

 {'ip_src': '3.3.3.3',
  'ip_dst': '4.4.4.4',
  'src': 47,
  'src_name': 'test2',
  'dst': 41,
  'dst_name': 'test1'},

i want to remove the duplicate data connection because the src and dst maybe diffrent but its on the same cable.

so i want that my list will look like this:

 {'ip_src': '2.2.2.2',
  'ip_dst': '1.1.1.1',
  'src_id': 43,
  'src_name': 'test1',
  'dst_id': 48,
  'dst_name': 'test2'},


 {'ip_src': '4.4.4.4',
  'ip_dst': '3.3.3.3',
  'src_id': 41,
  'src_name': 'test1',
  'dst_id': 47,
  'dst_name': 'test2'},

I try to comper every item in the list and make a reves but it didnt work because after i look into it ,i realised that the oreder of the items in the disctionary must be 100% revese and not only the value.

someone have any idea how to solve my problem?

CodePudding user response：

There are many ways to do it, but simplest one is to convert it to dict with (src_ip, dest_ip) as keys, by dict property duplicates will be removed.

l = [{'ip_src': '2.2.2.2',
  'ip_dst': '1.1.1.1',
  'src_id': 43,
  'src_name': 'test1',
  'dst_id': 48,
  'dst_name': 'test2'},

 {'ip_src': '1.1.1.1',
  'ip_dst': '2.2.2.2',
  'src': 48,
  'src_name': 'test2',
  'dst': 43,
  'dst_name': 'test1'},


 {'ip_src': '4.4.4.4',
  'ip_dst': '3.3.3.3',
  'src_id': 41,
  'src_name': 'test1',
  'dst_id': 47,
  'dst_name': 'test2'},

 {'ip_src': '3.3.3.3',
  'ip_dst': '4.4.4.4',
  'src': 47,
  'src_name': 'test2',
  'dst': 41,
  'dst_name': 'test1'}]

temp_l = {tuple(sorted([i['ip_src'], i['ip_dst']])): i for i in l}
final = list(temp_l.values())

print(final)

# [{'ip_src': '1.1.1.1',
#   'ip_dst': '2.2.2.2',
#   'src': 48,
#   'src_name': 'test2',
#   'dst': 43,
#   'dst_name': 'test1'},
#  {'ip_src': '3.3.3.3',
#   'ip_dst': '4.4.4.4',
#   'src': 47,
#   'src_name': 'test2',
#   'dst': 41,
#   'dst_name': 'test1'}]
