Question

doc_holder_str = ''
sample_H_value = open("C:\testGupixwin\BX-N-H.HED", "r")
standard_conc_value = open("C:\testGupixwin\gupixwin_H_stdConc.txt", "r")
sample_H_value_str = sample_H_value.readline()
while sample_H_value_str is not '' :
    stripper_sample_H = float(sample_H_value_str[5:].lstrip(' '))

我正在尝试编写一段代码（如上所示），它读取一些值，对其进行一些计算并返回所述值。我正在使用LiClipse IDE，用于python。

我已经测试了我的代码并且它可以工作，但是当我尝试使用真实数据运行它时（为此我创建了一个新文件夹以放入我将使用的所有文件中）我收到操作系统错误，提示我插入了无效的参数。

错误报告说;

Traceback (most recent call last):
File "C:\Python34\workspace\Gupixwin_Project.py", line 11, in <module>
sample_H_value = open("C:\testGupixwin\BX-N-H.HED", "r")
OSError: [Errno 22] Invalid argument: 'C:\testGupixwin\\BX-N-H.HED'

点击C:\testGupixwin\\BX-N-H.HED会弹出一个消息框，提示，我引用，

该定义见于C：\ testGupixwin \ BX-N-H.HED，（其中无法打开，因为它是一个已编译的扩展名）

我必须指出，我觉得错误是系统看到...... \\ BX-N ....而不是.. \ BX-N ...我期待的。

有人建议我这样做

[打开窗口 - ＆gt;偏好，转到PyDev - ＆gt;编辑 - ＆gt;代码风格 - ＆gt; 文件类型，查找“有效源文件（逗号分隔）”并追加 “，记录”。]

我已经完成了这一点但我仍然得到了OSERROR报告。

感谢您的帮助

我认为问题在于public static bool RemoveDrive(string driveCharWithColon) { // open the storage volume IntPtr hVolume = CreateFile(@"\\.\" + driveCharWithColon, 0, FILE_SHARE_READ | FILE_SHARE_WRITE, IntPtr.Zero, OPEN_EXISTING, 0, IntPtr.Zero); if (hVolume.ToInt32() == -1) return false; // get the volume's device number long DeviceNumber = GetDeviceNumber(hVolume); if (DeviceNumber == -1) return false; // get the drive type which is required to match the device numbers correctely string rootPath = driveCharWithColon + "\\"; DriveType driveType = GetDriveType(rootPath); // get the dos device name (like \device\floppy0) to decide if it's a floppy or not - who knows a better way? StringBuilder pathInformation = new StringBuilder(250); uint res = QueryDosDevice(driveCharWithColon, pathInformation, 250); if (res == 0) return false; // get the device instance handle of the storage volume by means of a SetupDi enum and matching the device number long DevInst = GetDrivesDevInstByDeviceNumber(DeviceNumber, driveType, pathInformation.ToString()); if (DevInst == 0) return false; // get drives's parent, e.g. the USB bridge, the SATA port, an IDE channel with two drives! int DevInstParent = 0; CM_Get_Parent(ref DevInstParent, (int)DevInst, 0); // Lock and dismount the volume. bool e = LockVolume(hVolume); int error = Marshal.GetLastWin32Error(); bool f = DismountVolume(hVolume); int error2 = Marshal.GetLastWin32Error(); // Close the volume so other processes can use the drive. if (!CloseVolume(hVolume)) return false; for (int tries = 1; tries <= 3; tries++) // sometimes we need some tries... { int r = CM_Request_Device_Eject_NoUi(DevInstParent, IntPtr.Zero, null, 0, 0); if (r == 0) return true; Thread.Sleep(500); } return false; }

的转义

将字符串替换为：\ 用：

open("C:\testGupixwin\BX-N-H.HED", "r")

_{（也在以下行中执行此操作）}

LiClipse Python
