I'm not excited about suggesting the walrus operator when people want to chain mutating method calls like this. It results in ugly code with way too many parentheses and a distinctly un-Pythonic flavor. I hope the OP doesn't go off and infect a whole subcommunity with this idiom.
Not a huge fan the walrus operator, yet. I don't think I'll use it unless necessary.
I'll stick to a = list() and then a.append() in this case

How you can do it with warus operator.
>>> (xs := list(range(10))).append(42)
>>> xs
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 42]
