#解析数据 detail_selector = parsel.Selector(detail_html) title = detail_selector.css('.b_crumb_cont *:nth-child(3)::text').get() comment = detail_selector.css('.title white::text').get() view_count = detail_selector.css('.view_count::text').get() date = detail_selector.css('#js_mainleft > div.b_foreword > ul > li.f_item.when > p > span.data::text').get() days = detail_selector.css('#js_mainleft > div.b_foreword > ul > li.f_item.howlong > p > span.data::text').get() money = detail_selector.css('#js_mainleft > div.b_foreword > ul > li.f_item.howmuch > p > span.data::text').get() character = detail_selector.css('#js_mainleft > div.b_foreword > ul > li.f_item.who > p > span.data::text').get() play_list = detail_selector.css('#js_mainleft > div.b_foreword > ul > li.f_item.how > p > span.data > span::text').getall() for play in play_list: print(play) print(title, comment, view_count, date, days, money, character, play_list, detail_url) time.sleep(random.randint(3,5))这段代码为什么只能输出最后一个网站的内容，应该怎么修改

这段代码只输出最后一个网站的内容是因为在循环中只是将每个play输出了，并没有将其他的信息输出。可以将每个网站的信息放在一个字典中，再将这些字典放在一个列表中，最后输出整个列表即可。修改后的代码如下：

detail_selector = parsel.Selector(detail_html)
title = detail_selector.css('.b_crumb_cont *:nth-child(3)::text').get()
comment = detail_selector.css('.title white::text').get()
view_count = detail_selector.css('.view_count::text').get()
date = detail_selector.css('#js_mainleft > div.b_foreword > ul > li.f_item.when > p > span.data::text').get()
days = detail_selector.css('#js_mainleft > div.b_foreword > ul > li.f_item.howlong > p > span.data::text').get()
money = detail_selector.css('#js_mainleft > div.b_foreword > ul > li.f_item.howmuch > p > span.data::text').get()
character = detail_selector.css('#js_mainleft > div.b_foreword > ul > li.f_item.who > p > span.data::text').get()
play_list = detail_selector.css('#js_mainleft > div.b_foreword > ul > li.f_item.how > p > span.data > span::text').getall()

result_list = []
for play in play_list:
    result_dict = {}
    result_dict['title'] = title
    result_dict['comment'] = comment
    result_dict['view_count'] = view_count
    result_dict['date'] = date
    result_dict['days'] = days
    result_dict['money'] = money
    result_dict['character'] = character
    result_dict['play'] = play
    result_dict['detail_url'] = detail_url
    result_list.append(result_dict)
    print(result_dict)

time.sleep(random.randint(3,5))

这样就能够输出每个网站的所有信息了。
