*大家好，我是 BeautifulSoup 的新手，我不太了解如何提取數(shù)據(jù)。我想提取亞馬遜暢銷書(shū)排行榜的前十個(gè)標(biāo)題并將其存儲(chǔ)到一個(gè)數(shù)組中。我的目標(biāo)是創(chuàng)建亞馬遜的前 10 名列表，并針對(duì)不同的類別一遍又一遍地復(fù)制該過(guò)程。我只想提取產(chǎn)品的“標(biāo)題”。這是我的代碼：*from bs4 import BeautifulSoupimport requestsheaders = {'User-Agent':'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_2) AppleWebKit/601.3.9 (KHTML, like Gecko) Version/9.0.2 Safari/601.3.9'}url_amazon = "https://www.amazon.co.uk/Best-Sellers-Electronics/zgbs/electronics"response = requests.get(url_amazon, headers = headers)soup = BeautifulSoup(response.content, "lxml")print(soup.prettify())title = soup.find("h1", class_ = "a-size-large a-spacing-medium zg-margin-left-15 a-text-bold").textprint(title)titles = []for item in soup.findAll("div", attrs = {"class" : "a-fixed-left-grid-col a-col-right"}):    name = item.find("div", attrs = {"class" : "p13n-sc-truncated"})    if name is not None:        titles.append(name.text)    else:        titles.append("unknown title")print(len(titles))for i in titles:    print(i)輸出是：“未知標(biāo)題”
