見出しとデータを含むリストをCSVに書き込む

Question

現在、CSVファイルを受け取り、CVEを抽出し、影響を受けるホストをリストに格納する影響を受ける小さなPython 3.6スクリプトを以下のように作成しています。

CVE-2009-1234 
10.11.1.1:80 
10.11.1.3:80 
10.11.1.4:80 
10.11.1.2:80 
10.11.1.22:80 
10.11.1.2:80 
10.11.1.27:80 
10.11.1.23:80 
10.11.1.29:80 
10.11.1.228:80 
CVE-2015-1234 
10.11.1.224:443 
10.11.1.224:80 
10.11.1.74:8080 
CVE-2015-1235 
10.11.1.22 
CVE-2017-1234 
10.11.1.22:443 
10.11.1.22:80 
10.11.1.73:8080 
CVE-2009-1235 
10.11.1.22:443 
10.11.1.22:80 

は、しかし、私は悩みので、各CVEをCSVファイルには、このデータの書き込みを持っていますし、ホストが例えば別々の列にある影響を受けています：

CVE-2009-1234 | CVE-2015-1234  | ... | 
-----------------+--------------------+-----+ 
10.11.1.1:80  | 10.11.1.224:443 |  | 
10.11.1.3:80  | 10.11.1.224:80  |  | 
10.11.1.4:80  | 10.11.1.74:8080 |  | 
10.11.1.2:80  |     |  | 
10.11.1.22:80 |     |  | 
10.11.1.2:80  |     |  | 
10.11.1.22:80 |     |  | 
10.11.1.23:80 |     |  | 
10.11.1.29:80 |     |  | 
10.11.1.228:80 |     |  | 

私が当初考えていたこと、私はリスト初期化場合CVEの数と同じサイズで、CVE番号のインデックス検索を行いました。新しいホストの対応するインデックスに各ホストを置くことができました。しかし、新しい行を初期化しようとすると難しくなりました。満たされました。

私はまた、CSVライブラリが明らかに正当な理由のためではないんです、列の機能を（挿入している天気を覗き込むか

次のように私の作業コードは次のとおりです。

import csv 

filename = 'report.csv' 
cve = set() 

data = [] 

with open(filename) as csvfile: 
    reader = csv.reader(csvfile, delimiter=',') 

    for row in reader: 
     if ',' in row[11]: 
      multi_cve = row[11].split(', ') 
      for entry in multi_cve: 
       cve.add(entry) 
     else: 
      cve.add(row[11]) 

    csvfile.seek(0) 

    for uniq_cve in cve: 
     data.append(uniq_cve) 
     for row in reader: 
      if row[2] == '': 
       full_address = row[0] 
      else: 
       full_address = row[0] + ':' + row[2] 

      if ',' in row[11]: 
       multi_cve = row[11].split(', ') 
       for entry in multi_cve: 
        if uniq_cve == entry: 
         data.append(full_address) 
      else: 
       if uniq_cve == row[11]: 
        data.append(full_address) 
     csvfile.seek(0) 

for entry in data: 
    print(entry)

Answer 1

は、私はそれが最善の解決策ではないかもしれない最終的には解決策になってしまったが、それは私の目的のために働く私がやったこと：

• の代わりに、私はその後、cve_listsで最長のリストを見つける私は リストcve_lists
• のリストを作成した1つのリストにすべてのものを挿入する - 私たちは最低でも必要な行数を教えてくれる

コードは次のとおりです。

CSVファイルのトイレを何

longest_list = len(max(cve_lists,key=len)) 

rows = [] 
row = [] 

# works out the maximum number of iterations we need to get all entries 
for count in range(0, (len(cve) * longest_list)): 
    for entry in cve_lists: 
     try: 
      row.append(entry[0]) 
      entry.pop(0) 
     except IndexError: 
      # if there is no index, we know there is no data and 
      # append a blank entry 
      row.append('') 

    rows.append(row) 
    row = [] 

with open(args.file , 'w') as resultFile: 
    wr = csv.writer(resultFile, dialect='excel') 
    wr.writerows(rows)
