在python中将以下数据转为json格式{"custBaseInfo":{"custType":"0","custName":"上海曜纵科技有限公司","company":"","custSource1":"1","custSource2":"108","provinceId":"31","cityId":"39","countryId":"459","tradeType":"51","firstTradeId":2031,"secondTradeId":203101,"remark":"","regionValue":["31","39","459"],"tradeValue":[2031,203101]},"contacts":[{"contactBaseInfo":{"name":"张三","gender":"1","duty":"","remark":"","state":1},"contactWays":[{"contactType":0,"contactInfo":"13325665254","state":0,"countryCode":86}],"phoneList":[{"contactType":0,"contactInfo":"13325665254","state":0,"countryCode":86}],"telList":[{"contactType":1,"contactInfo":"","state":0,"countryCode":86,"areaCode":"","extInfo":""}],"emailList":[{"contactType":6,"contactInfo":"","state":0}]}],"websites":[],"addresses":[],"custpoolId":""}

可以使用Python中的json模块将这个数据转换为json格式。具体代码如下：

import json

data = {
    "custBaseInfo": {
        "custType": "0",
        "custName": "上海曜纵科技有限公司",
        "company": "",
        "custSource1": "1",
        "custSource2": "108",
        "provinceId": "31",
        "cityId": "39",
        "countryId": "459",
        "tradeType": "51",
        "firstTradeId": 2031,
        "secondTradeId": 203101,
        "remark": "",
        "regionValue": ["31", "39", "459"],
        "tradeValue": [2031, 203101]
    },
    "contacts": [
        {
            "contactBaseInfo": {
                "name": "张三",
                "gender": "1",
                "duty": "",
                "remark": "",
                "state": 1
            },
            "contactWays": [
                {
                    "contactType": 0,
                    "contactInfo": "13325665254",
                    "state": 0,
                    "countryCode": 86
                }
            ],
            "phoneList": [
                {
                    "contactType": 0,
                    "contactInfo": "13325665254",
                    "state": 0,
                    "countryCode": 86
                }
            ],
            "telList": [
                {
                    "contactType": 1,
                    "contactInfo": "",
                    "state": 0,
                    "countryCode": 86,
                    "areaCode": "",
                    "extInfo": ""
                }
            ],
            "emailList": [
                {
                    "contactType": 6,
                    "contactInfo": "",
                    "state": 0
                }
            ]
        }
    ],
    "websites": [],
    "addresses": [],
    "custpoolId": ""
}

json_data = json.dumps(data)
print(json_data)

输出结果：

{"custBaseInfo": {"custType": "0", "custName": "\u4e0a\u6d77\u66dc\u7ef4\u79d1\u6280\u6709\u9650\u516c\u53f8", "company": "", "custSource1": "1", "custSource2": "108", "provinceId": "31", "cityId": "39", "countryId": "459", "tradeType": "51", "first...```

注意：这里的输出结果中，中文字符被转义成了Unicode编码。如果需要输出中文字符，请在dumps方法中添加参数ensure_ascii=False。
