[英]convert directed graph to Json file python
我正在将字典转换为有向图,然后尝试在此代码中将该图另存为JSON文件:
def main():
g = {"a": ["d"],
"b": ["c"],
"c": ["b", "c", "d", "e"],
"d": ["a", "c"],
"e": ["c"],
"f": []
}
graph = DirectedGraph()
for key in g.keys():
graph.add(key)
elements = g[key]
for child in elements:
graph.add_edge(key, child)
with open('JJ.json', 'w') as output_file:
json.dump(graph, output_file)
main()
它在json.dump给我一个错误
“ DirectedGraph”类型的对象不可JSON序列化
我该如何解决?
JSON模块仅知道如何序列化基本python类型。 在这种情况下使用转储添加对象(图形)时, 使用dict将任意Python对象序列化为JSON
我刚刚将代码编辑为:
with open(f'{string_input}.json', 'w') as output_file:
json.dump(graph.__dict__, output_file)
而且效果很好。
