看了一下wxPython、Python和Pythonwin的文档，没找到该用什么

求助，谢了

在csdn上有一个贴子，是使用win32api函数。

你给的链接一直无法连接，后来我google了一下，找到一个使用Perfermence Data Helper的例子
http://www.codeproject.com/atl/desktop_perf_mon.asp

照着样子自己用win32all的win32pdh包装了一个模块，放在附件里了，可以监视CPU使用情况的。非常简陋，不过大家感兴趣的话可以对它进行扩充。

我可以登录啊，这是上面的一个人给出的用win32api调用windows api得到相应的结果：

import win32wnet
import win32api

print win32wnet.WNetGetUser()  # 取机本名

print win32api.GetSystemInfo()

(0, 4096, 65536, 2147418111, 1, 1, 586, 65536, (15, 521))

上面GetSystemInfo

返回值类于
typedef struct _SYSTEM_INFO { 
  union { 
    DWORD  dwOemId; 
    struct { 
      WORD wProcessorArchitecture; 
      WORD wReserved; 
    }; 
  }; 
  DWORD  dwPageSize; 
  LPVOID lpMinimumApplicationAddress; 
  LPVOID lpMaximumApplicationAddress; 
  DWORD_PTR dwActiveProcessorMask; 
  DWORD dwNumberOfProcessors; 
  DWORD dwProcessorType; 
  DWORD dwAllocationGranularity; 
  WORD wProcessorLevel; 
  WORD wProcessorRevision; 
} SYSTEM_INFO;
