如何使用networkx库为对角启用的A*算法创建8个单元邻接映射

import networkx as nx

G = nx.Graph()

nodes = [1, 2, 3, 4, 5, 6, 7, 8]
G.add_nodes_from(nodes)

edges = [(1, 2), (1, 3), (2, 4), (2, 5), (3, 6), (3, 7), (4, 8), (5, 8), (6, 8), (7, 8)]
G.add_edges_from(edges)

def heuristic(node, target):
    return abs(node - target)

start_node = 1
target_node = 8
path = nx.astar_path(G, start_node, target_node, heuristic=heuristic)

print("最短路径：", path)
