搜索匹配文件（如果不可用）轉到下一個文件

Question

該程序搜索包含用戶定義的字符串的文件，然後讀取並根據某些匹配詞中的信息（即中間庫和倉庫，但它已經發現多個文件將包含給定的字符串，但不是中間等。我的問題是如何寫它，使程序將檢查文件的中間，如果它不存在然後搜索下一個，所以上？

以下是當前使用的代碼。

#!/usr/bin/python 

from subprocess import Popen, PIPE, call 
import sys, traceback 


s_REG=raw_input('Please enter Reg number: ') 

try: 
    a = Popen(["grep -l %s /shares/MILKLINK/PPdir/*/*.ini --exclude=\"/shares/MILKLINK/PPdir/*/conRtChp.ini\" " %s_REG], shell=True, stdout = PIPE) 
    FILE_DIR = a.communicate()[0] 
    FILE_DIR=FILE_DIR.rstrip('\n') 
    FILE=open("%s" %FILE_DIR , 'r') 
except IOError: 
    print "REG DOES NOT EXIST PLEASE CHECK .INI FILE: error code U1001\n" 
    print "Please consult Error Codes and meanings reference by viewing this program\n" 
    sys.exit(0) 

try: 
# Read File into array 
    for LINES in FILE: 
     if LINES.strip() == '[intermediate]': 
      break 
    for LINES in FILE: 
     if LINES.strip() == '[depotNum]': 
     break 
    if LINES.strip() == '[global]': 
      break 
     LINES = LINES.rstrip("\n").split(";") 
# Remove Blank Lines and whitespace 
     LINES = filter(None, LINES) 
# Ignore any lines that have been commented out 
     LINES = filter(lambda x: not x.startswith('#'), LINES) 
     for I in range(len(LINES)): 
    # Call the CrossRef Processor for each Reg to make sure for no differences 
      call(["/shares/optiload/prog/utilPRG/indref.sh", "%s" %LINES[I]]) 
except: 
    print "Cannot find Crossref creation script: error code U1002" 
    print "Please consult Error Codes and meanings reference by viewing this program\n" 
    sys.exit(0) 
FILE.close() 
try: 
    call(["/shares/optiload/prog/utilPRG/sortSs.sh"]) 
except: 
    print "Cannot find Crossref sort script: error code U1003" 
    print "Please consult Error Codes and meanings reference by viewing this program\n" 
    sys.exit(0)

import os 
#import re -- This module can be used for more advanced processings 

path = '/home/anmol/Desktop/test/testing/'#path of sample files 

files = [fiile for fiile in os.listdir(path) if '~' not in fiile] 
#this generates a list with the non-hidden files, hence using '~' 
#os.listdir() returns a list of all the files in a given directory. 

#os.listdir() = ['file 4.txt', 'file 5.txt', 'file 4.txt~', 'file 5.txt~', 
#'file2.txt', 'file1.txt~', 'file1.txt', 'file3.txt', 'file3.txt~', 'file2.txt~'] 

# After using '~' not in fiile 
# files = ['file 4.txt', 'file 5.txt', 'file2.txt', 'file1.txt', 'file3.txt'] 

for file_name in files: 
    document = open(path+file_name).read() #returns a string 
    refined_document = " ".join(document.split("\n")) # replaces \n with a space 
    if "intermediate" in refined_document or "depot" in refined_document: 
     #main working condition 
     print "The required word is found under :",file_name
