我DMOZ蜘蛛python腳本是在這裏

from scrapy import spiders 


class dmozspider(spiders): 
    name = "dmoz" 
    allowed_domains = ["dmoz.org"] 
    start_urls = [ 
     "http://www.dmoz.org/Computers/Programming/Languages/Python/Books/", 
     "http://www.dmoz.org/Computers/Programming/Languages/Python/Resources/" 
    ] 

    def parse(self, response): 
     filename = response.url.split("/")[-2] + '.html' 
     with open(filename, 'wb') as f: 
      f.write(response.body)

歡迎來到Stack Overflow Steve！將來，請嘗試使用四（4）個空格格式化代碼以創建代碼黑色（它非常有助於讀取/格式化）。另外，您是否可以驗證代碼是否已更正，並且顯示的新縮進是否準確？ – Rejected

問題是你正在導入「蜘蛛」，並將它用作你的基類。「蜘蛛」是包含蜘蛛的包，即Spider類。要使用它，請使用：

from scrapy.spiders import Spider 


class dmozspider(Spider): 
    ... # Rest of your code
