python中将多个数据生成嵌套的

原始数据

data = {
    "nodeDataArray": [
        {"category": "Start", "key": -1, "text": "start"},
        {"category": "Decision", "key": -9, "text": "jc-1", "value": "DS2021082018280100000000000001"},
        {"category": "Conditional", "key": -4, "text": "if"},
        {"category": "Decision", "key": -5, "text": "jc-2", "value": "DS2021082018281300000000000002"},
        {"category": "Conditional", "key": -6, "text": "if"},
        {"category": "Decision", "key": -7, "text": "jc-3", "value": "DS2021082018314100000000000003"},
        {"category": "Decision", "key": -8, "text": "jc-4", "value": "DS2021082417261100000000000004"},
        {"category": "Decision", "key": -10, "text": "jc-5", "value": "DS2021083109125200000000000005"}],
    "linkDataArray": [{"from": -1, "text": "", "to": -9},
                      {"from": -9, "text": "", "to": -4},
                      {"from": -4, "text": "符合", "to": -5, "visible": "true"},
                      {"from": -4, "text": "不符合", "to": -7, "visible": "true"},
                      {"from": -5, "text": "", "to": -6},
                      {"from": -6, "text": "符合", "to": -8, "visible": "true"},
                      {"from": -6, "text": "不符合", "to": -10, "visible": "true"}]
}

上面数据中key表示当前节点，from为to的前面一个节点。上面的key和下面的to是对应的

流程图如下

在linkDataArray中有的数据中是有"符合"和“不符合”的字样，通过上面数据生成一下的

{'DS2021082018280100000000000001': 'DS2021082018280100000000000001','if': {'true': {'DS2021082018281300000000000002': 'DS2021082018281300000000000002','if': {'true': {'DS2021082417261100000000000004': 'DS2021082417261100000000000004'},'false': {'DS2021083109125200000000000005': 'DS2021083109125200000000000005'}}},'false': {'DS2021082018314100000000000003': 'DS2021082018314100000000000003'}}}

其中为true的是在linkDataArray中符合的，false是对应的不符合，并且将嵌套到他的上一个节点from中，要是没有if判断的话就如下写法就好

{'DS2021082018280100000000000001': 'DS2021082018280100000000000001','DS2021082018281300000000000002':'DS2021082018281300000000000002'}

或者不按上面生成，生成比较易取，看起来舒服的一种数据格式也可以。

没太看懂是要干啥 另外json是“”，不是单引号，在线json都识别不了哦
