用于字典的Python字符串

我正在开发一个自定义的Freeradius Python模块。我在变量中的数据低于STRING类型。如何将其转换为字典。

[
 ["Acct-Input-Octets", "47762756"],
 ["NAS-Port-Type", "Ethernet"],
 ["Acct-Session-Id", "\"8172fde7\""],
 ["Acct-Output-Gigawords", "0"],
 ["Service-Type", "Framed-User"],
 ["Acct-Unique-Session-Id", "\"f55597d3cc05fe3a\""],
 ["Called-Station-Id", "\"myhome\""],
 ["Acct-Authentic", "RADIUS"],
 ["Acct-Status-Type", "Interim-Update"],
 ["Acct-Output-Packets", "698213"],
 ["NAS-IP-Address", "192.168.100.100"],
 ["NAS-Port-Id", "\"vlan555\""],
 ["Acct-Output-Octets", "379021490"],
 ["Acct-Session-Time", "33900"],
 ["Calling-Station-Id", "\"A0:CC:DD:9F:F2:09\""],
 ["Framed-Protocol", "PPP"],
 ["User-Name", "\"testing\""],
 ["NAS-Identifier", "\"testing_radius\""],
 ["Event-Timestamp", "\"Sep  6 2014 02:09:40 PKT\""],
 ["Acct-Input-Gigawords", "0"],
 ["Framed-IP-Address", "172.16.100.100"],
 ["Acct-Input-Packets", "622069"],
 ["NAS-Port", "467422"],
 ["Acct-Delay-Time", "0"]
]

所以，例如， 我想将下面的地图映射为一个关键的谷值

  

[＆＃34; Acct-Input-Octets＆＃34;，＆＃34; 7281436＆＃34;]

所以它应该是

  

data = {＆＃34; Acct-Input-Octets＆＃34; ：7281436}

有些情况下会有像

这样的转义报价
  

[＆＃34; NAS-Identifier＆＃34;，＆＃34; \＆＃34; testing_radius \＆＃34;＆＃34;]

我正在使用Python 2.6附带的CentOS 6.4

我使用json module：

dict(json.loads(inputstring))

json.loads()调用将字符串转换为Python列表。 dict()获取该列表中的键值对并从中构建字典。

将数值转换为整数是一个额外的步骤，但它可以集成：

dict((k, int(v) if v.isdigit() else v) for k, v in json.loads(inputstring))

演示：

>>> import json
>>> inputstring = r'''[["Acct-Input-Octets", "47762756"], ["NAS-Port-Type", "Ethernet"], ["Acct-Session-Id", "\"8172fde7\""], ["Acct-Output-Gigawords", "0"], ["Service-Type", "Framed-User"], ["Acct-Unique-Session-Id", "\"f55597d3cc05fe3a\""], ["Called-Station-Id", "\"myhome\""], ["Acct-Authentic", "RADIUS"], ["Acct-Status-Type", "Interim-Update"], ["Acct-Output-Packets", "698213"], ["NAS-IP-Address", "192.168.100.100"], ["NAS-Port-Id", "\"vlan555\""], ["Acct-Output-Octets", "379021490"], ["Acct-Session-Time", "33900"], ["Calling-Station-Id", "\"A0:CC:DD:9F:F2:09\""], ["Framed-Protocol", "PPP"], ["User-Name", "\"testing\""], ["NAS-Identifier", "\"testing_radius\""], ["Event-Timestamp", "\"Sep 6 2014 02:09:40 PKT\""], ["Acct-Input-Gigawords", "0"], ["Framed-IP-Address", "172.16.100.100"], ["Acct-Input-Packets", "622069"], ["NAS-Port", "467422"], ["Acct-Delay-Time", "0"]]'''
