我正在字符串中捕获仅de标记"a价格"；从搜索第一页的结果中；iphone"；在亚马逊网站上。
但是，结果包括以"；a价格"；，作为"；a-price a-text-price"；。我怎么能被我的抓取代码捕获而忽略这些标签？
遵循刮取代码：
s = BeautifulSoup(resp.content, features="lxml")
prices = s.find_all("span", attrs={
"class": "a-price"})
print(prices)
按照打印结果：

您可以使用CSS选择器[class="a-price"]只获取类别为a-price的标记，而不获取其他标记。
例如：
import requests
from bs4 import BeautifulSoup
url = 'https://www.amazon.com.br/s?k=iphone&__mk_pt_BR=%C3%85M%C3%85%C5%BD%C3%95%C3%91&ref=nb_sb_noss_2'
headers = {'User-Agent': 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0'}
soup = BeautifulSoup(requests.get(url, headers=headers).content, 'lxml')
for t in soup.select('[class="a-price"]'):
print(t)
print('-' * 80)
打印：
<span class="a-price" data-a-color="base" data-a-size="l"><span class="a-offscreen">R$6.226,87</span><span aria-hidden="true"><span class="a-price-symbol">R$</span><span class="a-price-whole">6.226<span class="a-price-decimal">,</span></span><span class="a-price-fraction">87</span></span></span>

... and so on.
尝试在find_all()函数中使用class_参数。
s = BeautifulSoup(resp.content, features="lxml")
prices = s.find_all("span", class_ = 'a-price'})
使用[print(''.join(list(t.stripped_strings))) for t in s.select('[class="a-price-whole"]')]
