[Python] Python Code to combine duplicated element

I have a list with duplicated some of element. And i need to combine some element based on the other duplicated element.

Example input:

[
('Sig: 7126', '10.3.5.0', 4),
('Sig: 7126', '10.3.5.0', 1),
('Sig: 7126', '10.3.5.0', 1),
('Sig: 3326', '10.3.5.0', 7),
('Sig: 7126', '10.3.5.1', 3),
('Sig: 7126', '10.3.5.1', 1),
('Sig: 7126', '10.3.5.2', 5),
('Sig: 7126', '10.3.5.2', 1),
('Sig: 7126', '10.3.5.4', 2),
('Sig: 7126', '10.3.5.4', 1),
('Sig: 7126', '10.3.5.4', 1),
('Sig: 7126', '10.3.5.4', 1),
('Sig: 0559', '10.3.5.34', 1),
('Sig: 7126', '10.3.5.34', 1),
('Sig: 7126', '10.3.5.34', 1),
('Sig: 0559', '10.3.5.42', 1),
('Sig: 7126', '10.3.5.42', 1),
('Sig: 7126', '10.3.5.43', 2)
]


What the goal is like this:

[
('Sig: 7126', '10.3.5.0', 6),
('Sig: 3326', '10.3.5.0', 7),
('Sig: 7126', '10.3.5.1', 4),
('Sig: 7126', '10.3.5.2', 6),
('Sig: 7126', '10.3.5.4', 5),
('Sig: 0559', '10.3.5.34', 1),
('Sig: 7126', '10.3.5.34', 2),
('Sig: 0559', '10.3.5.42', 1),
('Sig: 7126', '10.3.5.42', 1),
('Sig: 7126', '10.3.5.43', 2)
]


Is there any simple python code to achieve it ?
