我正在嘗試編寫一個(gè)檢查 Steam 商店的腳本，但在過濾掉代碼中沒有折扣的所有列表時(shí)遇到問題。我只想保留帶有 span 標(biāo)簽的列表以及<span>-percentage</span>其中的列表，而不是沒有的列表。這是我的代碼：from urllib.request import urlopenfrom datetime import dateimport requests as rqinp = str(input('what would you like to search up?'))w = ('https://store.steampowered.com/search/?term=' + inp)page = rq.get(w)soup = bsoup(page.content, 'html.parser')soup.prettify()sales = soup.find_all('div', class_="responsive_search_name_combined")for sale in sales: p = soup.find('div', class_="col search_price responsive_secondrow") d = soup.find_all('div', class_="col search_discount responsive_secondrow") n = soup.find('span', class_="title") if None in (d, n, p): continue print(d)和輸出（包含我想要過濾掉的東西/我想要保留的東西）<span>-16%</span></div>, <div class="col search_discount responsive_secondrow"></div>, <div class="col search_discount responsive_secondrow"><span>-19%</span></div>, <div class="col search_discount responsive_secondrow"></div>, <div class="col search_discount responsive_secondrow"></div>, <div class="col search_discount responsive_secondrow"></div>, <div class="col search_discount responsive_secondrow"></div>, <div class="col search_discount responsive_secondrow"></div>, <div class="col search_discount responsive_secondrow"></div>, <div class="col search_discount responsive_secondrow"></div>, <div class="col search_discount responsive_secondrow"></div>, <div class="col search_discount responsive_secondrow"></div>, <div class="col search_discount responsive_secondrow"></div>, <div class="col search_discount responsive_secondrow"></div>, <div class="col search_discount responsive_secondrow"></div>, <div class="col search_discount responsive_secondrow"></div>, <div class="col search_discount responsive_secondrow"></div>, <div class="col search_discount responsive_secondrow">等等，我嘗試替換d = soup.find_all('div', class_="col search_discount responsive_secondrow")為，d = soup.find_all('span', string="-16%")看看是否有效，但沒有。我想保留 span 標(biāo)簽，但不保留 div 標(biāo)簽，有人可以幫忙嗎？

您只需try-except在最后一個(gè)for循環(huán)中添加一個(gè)塊即可解決您的問題。這是完整的代碼：
from urllib.request import urlopen
from datetime import date
import requests as rq
from bs4 import BeautifulSoup as bsoup
inp = str(input('what would you like to search up?'))
w = ('https://store.steampowered.com/search/?term=' + inp)
page = rq.get(w)
soup = bsoup(page.content, 'html.parser')
soup.prettify()
sales = soup.find_all('div', class_="responsive_search_name_combined")
final = []
for sale in sales:
p = soup.find('div', class_="col search_price responsive_secondrow")
d = soup.find_all('div', class_="col search_discount responsive_secondrow")
n = soup.find('span', class_="title")
try:
for element in d:
span = element.span
if span:
final.append(span.text)
except:
pass
print(final)
輸出：
what would you like to search up?>? among us
['-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%', '-10%', '-25%']
