dictとリスト変換パーサへのcsvの不明なバグ

Question

DictReader関数を使用して私のプログラムにcsvファイルでロードしました。私の仕事は、csvファイルの各列を、「ファイル名」と数を加えた別のリストに追加することです。いったんdictに変換されると、私はこのコードを使用しますが、最初の一時的なリストだけを最終的なdictに追加します。誰かがここで問題を指摘してくれますか？すべてのヘルプは非常に感謝をいただければ幸いです

{'filename1': ['Indian Standard Time', 
    'Indian Standard Time', 
    'Indian Standard Time', 
    'Indian Standard Time', 
    'Indian Standard Time', 
    'Indian Standard Time', 
    'Central Time Zone (North America)',

：

import csv 
with open(cities_new, 'r') as g: 
    files = csv.DictReader(g) 
    filenames = ['name', "timeZone_label", "utcOffset", "homepage", 
    "governmentType_label", 
    "isPartOf_label", "areaCode", "populationTotal", "elevation", 
    "maximumElevation", "minimumElevation", "populationDensity", 
    "wgs84_pos#lat", "wgs84_pos#long", "areaLand", "areaMetro", 
    "areaUrban"] 

    dict_1 = {} 
    count_2 = 0 
    for name in filenams: 
     lst = [] 
     for row in files: 
      lst.append(row[name]) 
     count_2+=1 
     dict_1['filename'+str(count_2)] = lst 

は、ここに私の出力です。 ここに、csvファイルの行ごとのプレーンテキストコピーがあります。私は5行にカットしましたが、まだ長いです。

Answer 1

あなたは繰り返しファイルから読み取るしようとしているが、ファイルが明示的に再び同じデータを読み取ることができるように、再びスタートにファイルを「巻き戻し」する必要が終わりに達した後。

g.seek(0)でこれを行うことができますが、ファイル全体を再読することはむしろ非効率的です。

たらを読んで、あなたの代わりにループを反転：

dict_1 = {} 
for row in files: 
    for count, name in enumerate(filenames): 
     key = 'filename{}'.format(count) 
     value = row[name] 
     dict_1.setdefault(key, []).append(value) 

私はenumerate()機能をインクリメントあなたマニュアルcount_2を置き換えます。
