合併文件，但只在標題行輸出

Question

我見過一些以前的文章有解決方案，爲別人工作，但由於某種原因一直沒有爲我工作。我試圖編寫一個python腳本來合併3個具有相同格式的文件，2）刪除重複的頭只，3）排序行Specimen_ID，和4）在每個行之間添加2個新的空行獨特的Specimen_ID（也就是說，除了第一個實例，由於頭部的原因，每三行都需要第4行）。

我有一個腳本，前兩個和最後一步工作的一部分：

import glob 

read_files = glob.glob("*.txt") 

header_saved = False 
linecnt=0 
with open("merged_data.txt", "wb") as outfile: 
    for f in read_files: 
     with open(f, "rb") as infile: 
      header = next(infile) 
      if not header_saved: 
       outfile.write(header) 
       header_saved = True 
      for line in infile: 
       outfile.write(line) 
       linecnt=linecnt+1 
       if (linecnt%3)==0: 
        outfile.write("\n\n") 

分揀行有什麼建議？另外，如果數據從製表符分隔的txt文件中導出Excel，我發現該腳本只會導致包含第一個infile的內容的輸出，而不會導致其他輸出。如果我只是將數據複製並粘貼到新的txt文件中並將它們用作infiles，那麼我沒有任何問題。有誰知道我爲什麼遇到這個問題？

您的解決方案應該是工作完美，除非有一些意想不到的數據文件。我剛添加的代碼爲您的第三個項目

read_files = glob.glob("*.txt") 

header_saved = False 
linecnt=0 
with open("merged_data.txt", "wb") as outfile: 
    for f in read_files: 
     with open(f, "rb") as infile: 
      header = next(infile) 
      if not header_saved: 
       outfile.write(header) 
       header_saved = True 
      for line in infile: 
       outfile.write(line) 
       linecnt=linecnt+1 
       if (linecnt%3)==0: 
        outfile.write("\n\n")
