python使用ctypes模块调用windowsapi获取系统版本示例

        elif os.dwMajorVersion==6 and os.dwMinorVersion==0:
            verStr = "windows vista"; # or 2008
        elif os.dwMajorVersion>=0:
            verStr = "windows 7";
        else:
            verStr = "unknown version";
    else:
        return "unknown Version";
    return verStr+" build"+str(os.dwBuildNumber)+" "+ctypes.string_at(os.szCSDVersion);

if __name__ == "__main__":
    print(GetSystemVersionString());
