filter out “reversed” duplicated tuples from a list in Python

Question

I\'ve a list like this:

[(\'192.168.1.100\', \'192.168.1.101\', \'A\'), (\'192.168.1.101\', \'192.168.1.100\', \'A\'), 
 (\'192.168.1.103\', \'192.168.1.101\         


        

Answer 1

>>> L=[('192.168.1.100', '192.168.1.101', 'A'), ('192.168.1.101', '192.168.1.100', 'A'), 
...  ('192.168.1.103', '192.168.1.101', 'B'), ('192.168.1.104', '192.168.1.100', 'C')]
>>> set(tuple(sorted((a,b))+[c]) for a,b,c in L)
set([('192.168.1.100', '192.168.1.104', 'C'), ('192.168.1.100', '192.168.1.101', 'A'), ('192.168.1.101', '192.168.1.103', 'B')])
