我們如何通過使用csv數據或作為列表提供的數據在python中動態創建json文件data.csv 看起來像這樣busi,bizthank,pumpthank,suchthank,merri它顯示了圖中節點之間的鏈接/邊。我正在嘗試構建節點和數組的 json，但出現 json 序列化錯誤。nodes = []nodes_dict = {}counter = 0edges = open(edges_file)    for line in edges:        line = line.replace("\n","")        source =  line.split(",")[0]        target = line.split(",")[1]        if source not in nodes_dict:            node_arr = {"name:" + source  + "," + "group:1"}            nodes.append(node_arr)            nodes_dict[source] = counter            counter += 1        if target not in nodes_dict:            node_arr = {"name:"+ target + "," + "group:1"}            nodes.append(node_arr)            nodes_dict[target] = counter            counter += 1 json.dumps(nodes,outputfile)但我收到此錯誤類型錯誤：{'name:busi,group:1'} 不是 JSON 可序列化的我想要的輸出 "nodes":[    {"name":"Myriel","group":1},        {"name":"Napoleon","group":1},{"name":"Mme.Hucheloup","group":8}],"links":            [{"source":1,"target":0,"value":1},{"source":2,"target":0,"value":8},                {"source":3,"target":0,"value":10},{"source":3,"target":2,"value":6}}}
