基于操作系统版本，如何使用Python遍历目录？

Question

我正在尝试将存储在列表中的文件与服务器上可能是W2K3或W2K8的同一个文件进行比较。我试着用一个函数来处理这个问题，但是我被这个if语句卡住了。我正在尝试找出如何将正确的目录路径放入os.walk():

    if osVer == 'serverW2k3':
        continue
    elif osVer == 'serverW2k8':
        for folder, subfolders, files in os.walk():

我以前确实做过，但有重复的行，所以我想简化代码。 以下是全班同学：

class checkstatus:
    def __init__(self):
        print 'Checking Status...'
        chkbkpstats = csv.reader(file('c://temp//networkerservers.csv'))

        srvrs = []
        for row in chkbkpstats:
            srvrs.append({'Name' : row[0], 'Instance' : row[1]})

        for srvr in srvrs:
            srvrName = (srvr['Name'])
            srvrInst = (srvr['Instance'])
            w2k3Chk = r'\\%s\d$\DA$Utils\log\networker' % srvrName
            w2k8Chk = r'\\%s\c$\ProgramData\SQL\DA$Utils\log\networker' % srvrName

            try:
                c = wmi.WMI(srvr['Name'])

            except:
                print 'Error connecting to %s to check OS version' % srvrName

            else:
                osVer = c.Win32_OperatingSystem()[0].Caption
                if '2003' in osVer:
                    return 'serverW2k3'
                    #self.fileCheck(w2k3Chk, w2k8Chk, srvrInst, srvrName)

                elif '2008' in osVer:
                    return 'serverW2k8'
                    #self.fileCheck(w2k3Chk, w2k8Chk, srvrInst, srvrName)

    def fileCheck(self, w2k3Chk, w2k8Chk, srvrInst, srvrName, osVer):
        found = False
        if osVer == 'serverW2k3':
            continue
        elif osVer == 'serverW2k8':
            for folder, subfolders, files in os.walk():
                for sqlFile in files:
                    if sqlFile == srvrInst + ".log":
                        found = True
                        print 'The Backup For %s on %s Still Running' % (srvrInst, srvrName)
                    elif sqlFile == (srvrInst + ".ok"):
                        found = True
                        print 'The Backup For %s on %s Completed Successfully' % (srvrInst, srvrName)
                    elif sqlFile == (srvrInst + ".err"):
                        found = True
                        print 'The Backup For %s on %s Has Failed' % (srvrInst, srvrName)
                if not found:
                    print 'No file for %s found on %s' % (srvrInst, srvrName)

Answer 1

这是我更新的函数代码的狙击手。你知道吗

        else:
            osVer = c.Win32_OperatingSystem()[0].Caption
            if '2003' in osVer:
                self.fileCheck(srvrInst, srvrName, osVer, w2k3Chk, w2k8Chk)

            elif '2008' in osVer:
                self.fileCheck(srvrInst, srvrName, osVer, w2k3Chk, w2k8Chk)

def fileCheck(self, srvrInst, srvrName, osVer, w2k3Chk, w2k8Chk):
    found = False
    if '2003' in osVer:
        path = w2k3Chk
    elif '2008' in osVer:
        path = w2k8Chk
    for folder, subfolders, files in os.walk(path):

Answer 2

您的问题有点不清楚，而且您的示例代码显然不是您真正的代码（您不能调用os.步行但我想我能猜到你在找什么。你知道吗

首先，改变fileCheck如下：

def fileCheck(self, path, srvrInst, srvrName):
    found = False
    for folder, subfolders, files in os.walk(path):
        ...

现在，在__init__中，像这样做最后一部分：

else:
    osVer = c.Win32_OperatingSystem()[0].Caption
    if '2003' in osVer:
        self.fileCheck(w2k3Chk, srvrInst, srvrName)
    else:
        self.fileCheck(w2k8Chk, srvrInst, srvrName)
