获取属性名称

Question

我想在迭代它时获取任何属性的名称。

的ts3defines.py看起来像this：

class VirtualServerProperties(object): 
    VIRTUALSERVER_UNIQUE_IDENTIFIER = 0 
    VIRTUALSERVER_NAME = 1 
    VIRTUALSERVER_WELCOMEMESSAGE = 2 
    VIRTUALSERVER_PLATFORM = 3 
    VIRTUALSERVER_VERSION = 4 
    VIRTUALSERVER_MAXCLIENTS = 5 
    VIRTUALSERVER_PASSWORD = 6 
    VIRTUALSERVER_CLIENTS_ONLINE = 7 
    VIRTUALSERVER_CHANNELS_ONLINE = 8 
    VIRTUALSERVER_CREATED = 9 
    VIRTUALSERVER_UPTIME = 10 
    VIRTUALSERVER_CODEC_ENCRYPTION_MODE = 11 
    VIRTUALSERVER_ENDMARKER = 12 

的getItems(object)功能看起来像this：

def getItems(object): 
    return [getattr(object, a) for a in dir(object) 
       if not a.startswith('__') and not callable(getattr(object, a))] 

有问题的代码看起来像this：

for var in getItems(ts3defines.VirtualServerProperties): 
    (err, var) = ts3.getServerVariable(schid, var) 
    if err == ts3defines.ERROR_ok and var != "" and var != 0: 
     i.append('{0}: {1}'.format(var.__name__, var)) 

我的问题是关于var.__name__不应该返回字符串VIRTUALSERVER_BLA等？

它为什么会导致？

我不明白你为什么要访问__name__。您的getItems方法中已有名称;它是a。你应该返回并在循环中使用它。

def getItems(object): 
    return [(a, getattr(object, a)) for a in dir(object) 
      if not a.startswith('__') and not callable(getattr(object, a))] 

...

for name, var in getItems(ts3defines.VirtualServerProperties): 
    (err, var) = ts3.getServerVariable(schid, var) 
    if err == ts3defines.ERROR_ok and var != "" and var != 0: 
     i.append('{0}: {1}'.format(name, var))
