如何在python中将图json文件转换为图邻接列表文件？

Question

我在python中有图的json文件，我想解析它，并将其写为邻接表文件，如下所示。 有人可以帮我吗？

A B
C A
D Z

其中第一栏和第二栏是节点。 我没有.json文件的经验，这是我的json文件对图形的外观。

   "edges": [
            {
                "data": {
                    "cost": 0.01,
                    "source": "HBA2",
                    "target": "HBB"
                }
            },
            {
                "data": {
                    "cost": 0.598835,
                    "source": "HBA2",
                    "target": "EGFR"
                }
            },
            {
                "data": {
                    "cost": 0.594442,
                    "source": "HBA2",
                    "target": "DAXX"
                }
            },
            {
                "data": {
                    "cost": 0.598835,
                    "source": "HBA2",

                }
            },
            {
                "data": {
                    "cost": 0.598835,

                }
            },
            {
                "data": {
                    "cost": 0.598835,
                    "source": "HBA2",
