Use the "key" argument of "sort" and provide a key function that negates the first item of the tuple. – Michael Butscher Aug 30 '22 at 14:58

This will do it:
l = [(3,4),(4,5),(4,6)]
l = sorted(l, key= lambda x: (-x[0], x[1]))
print(l)
Output:
[(4, 5), (4, 6), (3, 4)]

Try this:
lst = [(3,4),(4,6),(4,5)]
lst.sort(key=lambda x: x[1])
lst.sort(key=lambda x: x[0], reverse=True)
print(lst)
Output:
[(4, 5), (4, 6), (3, 4)]
