Question

打開一些參考我的網址https://cars.mail.ru/reviews/renault/?year=2010-2016 和我應該開在那裏

https://cars.mail.ru/reviews/renault/sandero_stepway/2015/143355/ 
https://cars.mail.ru/reviews/renault/sandero/2015/147850/ 
https://cars.mail.ru/reviews/renault/sandero/2012/147529/ 
https://cars.mail.ru/reviews/renault/duster/2014/147433/ 
https://cars.mail.ru/reviews/renault/logan/2011/146991/ 
https://cars.mail.ru/reviews/renault/duster/2015/146645/ 

我需要打開所有的鏈接和旁邊的一個頁面，並有開放所有鏈接。 我該如何快速做到這一點？ 如果我使用

models = ['11', '12', '14', '15', '16', '17', '18', '19', '20', '21', '25', '30', '4', '5', '6', '9', 
    'avantime', 'clio', 'clio_rs', 'duster', 'espace', 'estafette', 'express', 'fluence', 
    'fuego', 'grand_espace', 'grand_scenic', 'kangoo', 'kaptur', 'koleos', 'laguna', 'latitude', 
    'logan', 'mascott', 'master', 'megane', 'megane_rs', 'modus', 'safrane', 'sandero', 'sandero_stepway', 
    'scenic', 'symbol', 'trafic', 'twingo', 'vel_satis'] 
years = ['2010', '2011', '2012', '2013', '2014', '2015', '2016'] 
pattern = 'https://cars.mail.ru/reviews/renault/' 

for model in models: 
    for year in years: 
     for i in range(143350, 143360): 
      res = pattern + model + '/' + year + '/' + str(i) 
      try: 
       page = urllib2.urlopen(res).read() 
       print page 
       soup = BeautifulSoup(page, 'html.parser') 
      except: 
       continue 

它需要這麼多時間

Answer 1

你正在做

len(models) * len(years) * (143360 - 143350) # 3220 

HTTP請求。如果每個人只需要一秒鐘，你就會忙了近一個小時。您可以嘗試multiprocessing。
