AttributeError: can't set attribute in python

Question

Here is my code

N = namedtuple(\"N\", [\'ind\', \'set\', \'v\'])
def solve()
    items=[]
    stack=[]
    R = set(range(0,8))
    for i in range(0,8):
              


        

Answer 1

items[node.ind] = items[node.ind]._replace(v=node.v)

(Note: Don't be discouraged to use this solution because of the leading underscore in the function _replace. Specifically for namedtuple some functions have leading underscore which is not for indicating they are meant to be "private")
