Isn’t it better for reverse linked list to be done in more concise code:
node, prev = head, None
while node:
t, node.next = node.next, prev
prev, node = node, t
return prev
Not necessarily. While concise and clean code is often a good thing to strive for, I would caution against sacrificing readability. In this case, your code is extremely concise, but not super clear what is going on.
