python将字符串转换为字典json

字符串输出具有以下值：

interface Vlan364
  ip policy route-map RM_OUT
interface Vlan234
  ip policy route-map RM_OUT
interface Vlan235
  ip policy route-map RM_OUT
interface Ethernet1/2
  ip policy route-map RM_IN
interface Ethernet1/6
  ip policy route-map RM_IN

1如何将其转换为disctionary，以便disctionary outputDict如下所示：

{
 "interface":"Vlan364", "ip policy route-map":"RM_OUT",
 "interface":"Vlan234", "ip policy route-map":"RM_OUT",
 "interface":"Vlan235", "ip policy route-map":"RM_OUT",
 "interface":"Ethernet1/2", "ip policy route-map":"RM_IN",
 "interface":"Ethernet1/6", "ip policy route-map":"RM_IN",
}

这里的目标是识别与每个接口关联的ip策略路由图

2如何在上面的讨论中找到唯一的ip策略路由图并将其放入列表中。i、 e.上述讨论的结果将是：

 route-map_list = [RM_OUT, RM_IN]

您可以使用正则表达式匹配关键字，然后使用user re.finditer搜索所有匹配项，并将匹配对象放入字典列表中

import re, json

output = """interface Vlan364
  ip policy route-map RM_OUT
interface Vlan234
  ip policy route-map RM_OUT
interface Vlan235
  ip policy route-map RM_OUT
interface Ethernet1/2
  ip policy route-map RM_IN
interface Ethernet1/6
  ip policy route-map RM_IN"""

output_list = []
route_map_list = []
REGEX_STRING = r"interface ([A-Za-z0-9//]+)[\n\r ]+ip policy route-map ([A-Z_]+)"
for match in re.finditer(REGEX_STRING,output):
    output_list.append(
        {
            "interface": match.group(1),
            "ip policy route-map": match.group(2)
        }
    )
    if match.group(2) not in route_map_list:
        route_map_list.append(match.group(2))

print(json.dumps(output_list, indent=4))
print(route_map_list)

输出：

[
    {
        "interface": "Vlan364",
        "ip policy route-map": "RM_OUT"
    },
    {
        "interface": "Vlan234",
        "ip policy route-map": "RM_OUT"
    },
    {
        "interface": "Vlan235",
        "ip policy route-map": "RM_OUT"
    },
    {
        "interface": "Ethernet1/2",
        "ip policy route-map": "RM_IN"
    },
    {
        "interface": "Ethernet1/6",
        "ip policy route-map": "RM_IN"
    }
]
['RM_OUT', 'RM_IN']

你能给我们看看你已经试过的代码吗？您遇到了什么问题？Python字典键必须是唯一的，即“outputDict”中只能有一个“interface”和一个“ip policy route map”，有关更多信息，请参阅，因此您可能必须先更新所需的输出。
