私のコードはほとんど機能しており、私は夢中になっています。csvファイルを取得し、行に番号を付け、列内のすべてのフィールドの文字数を見つけ、これらすべてを新しいcsvに書き込み、元のcsvファイルから他のすべての行を新しいcsvにコピーするコードがあります. （それが理にかなっていることを願っています）。

私のコード:

from csv import DictReader, DictWriter


with open('file1') as fil1,\ # Original file
     open('file2') as fil2,\ # File 2 (for line num and length headers)
     open('file3', 'wb') as fcompout,

# file3 is new file (to be original file +: line numbers and length of 'Name')

    read1 = DictReader(fil1)
    read2 = DictReader(fil2)

    writenum = DictWriter(fcompout, fieldnames=read2.fieldnames)
    writenum.writeheader()


    num = 0 # Number value
    for line1 in read1:
        newdic=dict(line1)
        fil2.seek(0) # resets the reader1 iterator
        for line2 in read2:
            num=num+1 # Number for line num
            outline1=dict(line2)
            outline1['Name']=newdic['Name']
            outline1['Length']=len(newdic['Name']) # Length of Name
            outline1['Line Num']=num # Line Numbers
            outline1['Geo Location']=newdic['Geo Location']
            outline1['IPStart']=newdic['IPStart']
            outline1['IPStop']=newdic['IPStop']
            outline1['Command']=newdic['Command']
            outline1['file']=newdic['file']
            outline1['NA']=newdic['NA']
            outline1['Default']=newdic['Default']
            writenum.writerow(outline1) # Write line to new csv

元のファイル (file1):

上記の file3 は、私のコードからの現在の出力です。file1 の最初の行が欠落していることに注意してください。別の行を最初に作成するように順序を変更しても問題ありません。常に最初の行が欠落しており、他のすべての行は完璧に見えます。私はそれを理解することはできません。

助けてください...

ありがとう、B0T

あなたがそこで何をしているのかよくわかりませんが、はるかに簡単です：

from csv import DictReader, DictWriter

with open('file1') as fil1, open('file2') as fil2, open('file3', 'wb') as fcompout:
    read1 = DictReader(fil1)
    read2 = DictReader(fil2)
    writenum = DictWriter(fcompout, fieldnames=read2.fieldnames)
    writenum.writeheader()

    for num, line in enumerate(read1):
        line['Length'] = len(line['Name']) # Length of Name
        line['Line Num'] = num+1           # Line Numbers
        writenum.writerow(line)            # Write line to new csv

これらの値をすべて再割り当てする必要はありません。必要なものを追加するだけです。

結果：

Line Num,Command,Name,Length,file,Geo Location,NA,Default,IPStart,IPStop
