You can use Counter from collections.

from collections import Counter l = [("192.168.1.1","high"),("192.168.1.1","high"),("192.168.1.1","low"),("192.168.1.1","low"),("192.168.1.2","high"),("192.168.1.2","medium")] counter = Counter(l) result = [(*key, counter[key]) for key in counter] 

If you don't care about order:

l = [("192.168.1.1","high"),("192.168.1.1","high"),("192.168.1.1","low"),("192.168.1.1","low"),("192.168.1.2","high"),("192.168.1.2","medium")] list(set([(*t, l.count(t)) for t in l]))
