How to remove the same pair with different order in values inside dictionary in Python?

Question

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 compare every item in the list and make a reverse but it didn’t work because after I look into it, I realised that the order of the items in the dictionary must be 100% reverse and not only the value.

Does someone have an idea how to solve my problem?

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'}]
