Question

嗨，我是python和regex的新手。我试图完成的任务是从字符串中提取信息：这是代码

import subprocess
import re

available = subprocess.check_output('netsh wlan show network mode=bssid',stderr=subprocess.STDOUT,universal_newlines=True,shell=True)
print(available)

输出是一个如下字符串：

Interface name : Wi-Fi 2 
There are 15 networks currently visible. 

SSID 1 : Rezalitchderk
    Network type            : Infrastructure
    Authentication          : WPA2-Personal
    Encryption              : CCMP 
    BSSID 1                 : 62:f1:89:7c:71:d1
         Signal             : 91%  
         Radio type         : 802.11n
         Channel            : 11 
         Basic rates (Mbps) : 1 2 5.5 11
         Other rates (Mbps) : 6 9 12 18 24 36 48 54

    SSID 2 : HUAWEI Mate 10 lite
        Network type            : Infrastructure
        Authentication          : WPA2-Personal
        Encryption              : CCMP 
        BSSID 1                 : 1c:15:1f:3f:87:f9
             Signal             : 82%  
             Radio type         : 802.11n
             Channel            : 11 
             Basic rates (Mbps) : 1 2 5.5 11
             Other rates (Mbps) : 6 9 12 18 24 36 48 54

现在我想用正则表达式检索＆＃34;之后的所有内容：＆＃34;

所以我尝试了这个data= re.findall(r':(.*)', available)

但结果并不完全符合我的要求：result of the regex

正则表达式的结果应该是：wi-fi 2，Rezalchiderk，Infrastructure，Wpa2-Personal ....

如何以正确的顺序获得结果？

感谢您的帮助。

使用 string.split 方法

A = '''Interface name : Wi-Fi 2 
There are 15 networks currently visible. 

SSID 1 : Rezalitchderk
    Network type            : Infrastructure
    Authentication          : WPA2-Personal
    Encryption              : CCMP 
    BSSID 1                 : 62:f1:89:7c:71:d1
         Signal             : 91%  
         Radio type         : 802.11n
         Channel            : 11 
         Basic rates (Mbps) : 1 2 5.5 11
         Other rates (Mbps) : 6 9 12 18 24 36 48 54

    SSID 2 : HUAWEI Mate 10 lite
        Network type            : Infrastructure
        Authentication          : WPA2-Personal
        Encryption              : CCMP 
        BSSID 1                 : 1c:15:1f:3f:87:f9
             Signal             : 82%  
             Radio type         : 802.11n
             Channel            : 11 
             Basic rates (Mbps) : 1 2 5.5 11
             Other rates (Mbps) : 6 9 12 18 24 36 48 54'''

res = []
for i in A.split("\n"):
    if ":" in i:
        val = i.split(" : ")[-1]
        print val.strip()
        res.append(val.strip())
