Python读取文件文件夹并检索

import os
import os.path

f=open("Shouldlist.txt")
ShouldList=[]
while 1:
   line =f.readline().strip('\n')
 #  print line
   if not line:
      break
   ShouldList.append(line)
# print ShouldList

rootdir="Z:\GETOT_BW"

ArriveFile=''

for parent,dirnames,filenames in os.walk(rootdir):
   ArriveFile=' '.join(filenames)

# print ArriveFile

ArriveNumber=0

for Item in ShouldList:
   if(ArriveFile.find(Item)>0):
      ArriveNumber+=1
   else:
      pass

print ArriveNumber

#print ShouldList[1]
#print ArriveFile[254:274]

此段代码主要是检索特定文件夹的全部文件，并对其进行检測，推断是否应到的file到到了。
