匹配索引值

-1

這是我當前的代碼。我想檢查兩個值（行）來檢查文件中的匹配項。匹配索引值

def checkOS(): 
    fid1 = open("C:/Python/NSRLOS.txt", 'r') 
    fid2 = open("C:/Python/sha_sub_hashes.out", 'r') 
    outdata = open("osMatches.txt", 'w') 
    line1 = fid1.readline() 
    line2 = fid2.readline() 
    while(line1 and line2): 
     xline= line1.split(',')[1] 
     yline = line2.split("|")[3] 
     zline = xline.replace('"','') 
     if (yline == zline): 
      outdata.append([yline , zline]) 
      print xline, zline 

if __name__=="__main__": 
    checkOS()

唯一的問題是我不知道我寫那有什麼，if語句之前，所有的代碼只是重新格式化，以便能夠從該行的指數拉。我想知道的是，如果我使用的陳述在這個意義上是有效的並且是有效的？然後我想輸出相等的值。下面是在文件中的某些行：

現在，你可能不會發現這幾行任何直接的比賽，但我知道，下了線的地方就會有至少一個比賽，因爲我看到了同時瀏覽文件。

你能給出一個來自每個文件的樣本行，應該被認爲是等效的或不等效的嗎？ – mVChr 2012-07-09 17:14:48

你有一個無限循環。 – mgilson 2012-07-09 17:17:04

而代碼會在if中產生'AttributeError'。 – 2012-07-09 17:19:30

你可能尋找的是這樣的：

使用with()它會自動關閉該文件爲您服務。

def checkOS(): 
    with open("C:/Python/NSRLOS.txt") as fid1,open("C:/Python/sha_sub_hashes.out") as fid2,open("osMatches.txt", 'w') as outdata: 
     for xline,yline in zip(fid1,fid2): #zip fetches lines from both files one by one           
      xline= xline.split(',')[1]  #use itertools.izip instead of zip if you're on python 2.x 
      yline = yline.split("|")[3] 
      zline = xline.replace('"','') 
      if yline == zline:     
       outdata.write("{0}{1}\n".format(yline , zline)) #use write to write the data back 

if __name__=="__main__": 
checkOS()

如果使用python 2.x，請考慮使用'itertools.izip'來防止將這兩個文件讀入內存。 – mgilson 2012-07-09 17:22:18
