有没有办法拆分字典键的值？

Question

我有一个很大的json文件，其中包含关于ip地址传输信息的信息。网络地址中的一个或多个块可以传输到另一个实体。我想进一步映射到参与转移的单个实体it。你知道吗

Transfers =[{
        "original_block": "87.118.128.0/18",
        "transferred_blocks": "87.118.144.0/22, 87.118.164.0/22",
        "from": "ITD Network SA",
        "to": "Bulgarian Telecommunications Company Plc.",
        "date": "16/07/2014",
        "transferType": "POLICY"
        }, {
        "original_block": "89.25.0.0/17",
        "transferred_blocks": "89.25.40.0/21, 89.25.52.0/22, 
                 89.25.56.0/21, 89.25.100.0/22, 89.25.124.0/22",
        "from": "ITD Network SA",
        "to": "Bulgarian Telecommunications Company Plc.",
        "date": "16/07/2014",
        "transferType": "POLICY"
        }, {
        "original_block": "94.155.0.0/17",
        "transferred_blocks": "94.155.104.0/21",
        "from": "ITD Network SA",
        "to": "Bulgarian Telecommunications Company Plc.",
        "date": "16/07/2014",
        "transferType": "POLICY"
        }]

with open ('Transfers','r') as t_list:#loads the json file
    dlist = json.load(t_list)

for k, v in dlist: dlist[k] = v("transferred_blocks").split(",")

预期输出如下：

dlist =[{
    "original_block": "87.118.128.0/18",
    "transferred_blocks": "87.118.164.0/22",

    "transferType": "POLICY"
    }, {
    "original_block": "89.25.0.0/17",
    "transferred_blocks": "89.25.40.0/21",

    "original_block": "89.25.0.0/17",

Answer 1

只需使用列表理解来迭代dlist中的每个dict，然后基于comma将ip地址列表拆分到transferred_blocks下，最后使用更新的ip addr从原始dict创建一个新dict

res = [dict(d, transferred_blocks=ip) for d in dlist for ip in d['transferred_blocks'].split(', ')]
print (json.dumps(res, indent=4))

输出
