Python 错误 os.walk IOError

Question

我尝试跟踪文件名中带有服务器的文件，并且我可以打印带有服务器**的目录中的所有文件，但是当我尝试读取该文件时，它给了我错误“说:

Traceback (most recent call last):
  File "view_log_packetloss.sh", line 27, in <module>
    with open(filename,'rb') as files:
IOError: [Errno 2] No such file or directory: 'pcoip_server_2014_05_19_00000560.txt'

我见过类似的问题，但我无法修复我的问题，使用 chdir 将当前目录更改为文件目录修复了一些错误。任何帮助表示赞赏。谢谢

#!usr/bin/env/ python
import sys, re, os

#fucntion to find the packetloss data in pcoip server files
def function_pcoip_packetloss(filename):
        lineContains = re.compile('.*Loss=.*')  #look for "Loss=" in the file
        for line in filename:
                if lineContains.match(line):    #check if line matches "Loss="
                        print 'The file has: '  #prints if "Loss=" is found
                        print line
                        return 0;

for root, dirs, files in os.walk("/users/home10/tshrestha/brb-view/logs/vdm-sdct-agent/pcoip-logs"):
        lineContainsServerFile = re.compile('.*server.*')
        for filename in files:
                if lineContainsServerFile.match(filename):
                        with open(filename,'rb') as files:
                                print 'filename'
                                function_pcoip_packetloss(filename);

文件是根目录中文件对象的名称。

dirpath is a string, the path to the directory. dirnames is a list of the names of the subdirectories in dirpath (excluding '.' and '..'). filenames is a list of the names of the non-directory files in dirpath. Note that the names in the lists contain no path components. To get a full path (which begins with top) to a file or directory in dirpath, do os.path.join(dirpath, name).

试试这个

for root, dirs, files in os.walk("/users/home10/tshrestha/brb-view/logs/vdm-sdct-agent/pcoip-logs"):
    lineContainsServerFile = re.compile('.*server.*')
    for filename in files:
            if lineContainsServerFile.match(filename):
                    filename = os.path.join(root, filename)
                    with open(filename,'rb') as files:
                            print 'filename:', filename
                            function_pcoip_packetloss(filename);
