獲取行號

Question

我有兩個文件：

文件1：

military troop deployment number need 

文件2：

foreign 1242 
military 23020 
firing 03848 
troop 2939 
number 0032 
dog 1234 
cat 12030 
need w1212 

我想從文件中讀取1行並打印它們在file2中的文字和行號。

我的輸出應該是這樣的：

military 2, troop 4, deployment <does not exist>, number 5, need 8 

我試過代碼：

words= 'military troop deployment number need' 
sent = words.split() 
print sent 

with open("file2","r") as f1: 
    for line_num,line in enumerate(f1): 
     if any([word in line for word in sent]): 
      print line_num, line 

這是打印所有行中，這些話都是。除此之外，它還打印了像軍事前，不必要的等字樣......我只需要那些確切的單詞和他們的行號。請幫助

Answer 1

您正在打印錯誤的東西。你想要打印不是整行的單詞。此外，如果您使用any，則不知道哪個詞匹配。

這裏有2種方法。第一個不檢測空條目。

words= 'military troop deployment number need' 
sent = words.split() 

matched = [] 
with open("file2","r") as f1: 
    for i, line in enumerate(f1): 
     for word in sent: 
      if word in line: 
       matched.append('%s %d' % (word, i + 1)) 

print ', '.join(matched) 

輸出：

military 2, troop 4, number 5, need 8

如果你要打印的空項爲好。

words= 'military troop deployment number need' 
sent = words.split() 

linenos = {} 

with open("file2","r") as f1: 
    for i, line in enumerate(f1): 
     for word in sent: 
      if word in line: 
       linenos[word] = i + 1 

matched2 = [] 
for word in sent: 
    if word in linenos: 
     matched2.append('%s %d' % (word, linenos[word])) 
    else: 
     matched2.append('%s <does not exist>' % word) 
print ', '.join(matched2) 

輸出：

military 2, troop 4, deployment <does not exist>, number 5, need 8 

爲了處理一個字並打印第一線的多個實例。

words= 'military troop deployment number need' 
sent = words.split() 
linenos = {} 

with open("file2", "r") as f1: 
    for i, line in enumerate(f1): 
     for word in sent: 
      if word in line: 
       if word in linenos: 
        linenos[word].append(i + 1) 
       else: 
        linenos[word] = [i + 1] 

matched2 = [] 
for word in sent: 
    if word in linenos: 
     matched2.append('%s %r' % (word, linenos[word][0])) 
    else: 
     matched2.append('%s <does not exist>' % word) 

print ', '.join(matched2) 

輸出與前面的例子相同。
