[Python]：命令中的双反斜杠

Question

小结：

我要执行一个pskill.exe命令。 在dos提示符下尝试过： C： \Users\JohanSA\Documents\EclipseWorkspace\ProdataATFBASE\src\resources\pskill.exe\本地主机-t 11780 --&加油！在

==>；但我想通过Python运行相同的命令。在

prodataOSLib.executeCmd("pskill.exe -t 11780", True, True)

-->；工作愉快！在

现在我想把计算机名加入pskill突击队

prodataOSLib.executeCmd("pskill.exe \\localhost -t 11780", True, True)

-->；这不起作用

登录executeCmd函数会显示：

11-04-2011 13:35:15 [prodataoslib-executeCmd] - DEBUG: Executing command: C:\Users\JohanSA\Documents\EclipseWorkspace\ProdataATFBASE\src\resources\pskill.exe \localhost -t 11780

——>；问题是单词“localhost”前面只有一个反斜杠-->；但是“localhost”之前怎么能有这两个反斜杠呢？在

有人能帮我吗？在

非常感谢！ 约翰

这是executeCmd函数：

def executeCmd (self,command, useResourceFolder=False, resultlogging=False):
    ''' Execute a command (default from current execution-folder) like you should type it in a DOS-prompt.
    Parameters:
    command = the command to be executed
    useResourceFolder = False (=default) or True --> set True if you want to execute a file from the resourcefolder.
    resultlogging = True when you want logging the result.
    return: List with result-messages or error-messages
    '''
    if useResourceFolder:
        command = os.path.abspath(os.path.join(self.currentdir, "..", "resources",command)) # Set path from resource directory            
    try:
        self.logger.debug("Executing command: %s" % command)
        output = subprocess.Popen(command, shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
        resultfile = output.stdout
        resultmessageList = []
        for i in resultfile.readlines():
            resultmessageList.append(i)  
        if resultlogging:
            if len(resultmessageList) > 0:
                resultstring=""
                for messageline in resultmessageList:
                    resultstring = resultstring + messageline.replace('\n', '')
                self.logger.debug("RESULT MESSAGE: %s " % resultstring)
        return resultmessageList
    except OSError, e:
        self.logger.error("Execution FAILED. Exception: %s" %(e))

通过加前缀r，使字符串成为原始字符串。我无法理解代码和描述，但您要查找的是原始字符串，它是通过前缀r获得的。像这样r'c:\localhost\nyprogram'
