繼上次發問pipelines的問題後，已經自行解決keyerror的問題，這次是無法寫入CSV檔，明明執行的時候都沒出現錯誤訊息，但就是寫不進去 CSV檔，附上程式碼 pipelines.py import csv from myproject.items import BirdTitle,BirdName,BirdCount class myPipeline(object): def __init__(self): self.myCSV = csv.writer(open('birds.csv','wb')) self.myCSV.writerow(['title','birdname','count']) def process_item(self, item,spider): titles=[] names=[] counts=[] for title in item: if isinstance(item, BirdTitle): for title in item['title']: titles.append(title) return titles for name in item: if isinstance(item, BirdName): for name in item['birdName']: names.append(name) return names for count in item: if isinstance(item,BirdCount): for count in item['count']: counts.append(count) return counts for a, b,c in zip(titles,names,counts): self.myCSV.writerow([a, b,c]) return item 請問我該如何解決? -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 210.70.151.159 ※ 文章網址: http://www.ptt.cc/bbs/Python/M.1420621249.A.CE1.html
