我想做的事：这个 HTML 代码：<img class="poster lazyload lazyloaded" data-src="https://image.tmdb.org/t/p/w94_and_h141_bestv2/3qlQM9KP1cyvNfPChA9rASASdHr.jpg" data-srcset="https://image.tmdb.org/t/p/w94_and_h141_bestv2/3qlQM9KP1cyvNfPChA9rASASdHr.jpg 1x, https://image.tmdb.org/t/p/w188_and_h282_bestv2/3qlQM9KP1cyvNfPChA9rASASdHr.jpg 2x" alt="Hitman" src="https://image.tmdb.org/t/p/w94_and_h141_bestv2/3qlQM9KP1cyvNfPChA9rASASdHr.jpg" srcset="https://image.tmdb.org/t/p/w94_and_h141_bestv2/3qlQM9KP1cyvNfPChA9rASASdHr.jpg 1x, https://image.tmdb.org/t/p/w188_and_h282_bestv2/3qlQM9KP1cyvNfPChA9rASASdHr.jpg 2x" data-loaded="true">我想提取“data-src”或“src”（或包含图像 URL 的每个属性）属性值。我试过的：Posters = soup.find("img")["src"]print(Posters)但这显然会返回每个 img 标签的所有值，因此每个链接都与海报无关。输出：https://www.themoviedb.org/assets/2/v4/logos/v2/blue_short-8e7b30f73a4020692ccca9c88bafe5dcb6f8a62a4c6bc55cd9ba82bb2cd95f6c.SVGhttps://www.themoviedb.org/assets/2/v4/logos/v2/blue_short-8e7b30f73a4020692ccca9c88bafe5dcb6f8a62a4c6bc55cd9ba82bb2cd95f6c.SVG对于海报，我指的是（检查此 URL https://www.themoviedb.org/search?&query=Hitman：）电影海报。概括我想在类“.lazyloaded”中提取属性内的值我希望一切都清楚。谢谢。

您可以尝试过滤class：
posters = soup.find_all("img", {"class": "lazyloaded"})
for poster in posters:
print(poster["src"])
请参阅文档：https ://www.crummy.com/software/BeautifulSoup/bs4/doc/#searching-by-css-class

假设您有以下文件demo.html：
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<img class="logo" src="https://image.tmdb.org/t/p/w94_and_h141_bestv2/3qlQM9KP1cyvNfPChA9rASASdHr.jpg">
<img class="poster lazyload lazyloaded"
data-src="https://image.tmdb.org/t/p/w94_and_h141_bestv2/3qlQM9KP1cyvNfPChA9rASASdHr.jpg"
data-srcset="https://image.tmdb.org/t/p/w94_and_h141_bestv2/3qlQM9KP1cyvNfPChA9rASASdHr.jpg 1x, https://image.tmdb.org/t/p/w188_and_h282_bestv2/3qlQM9KP1cyvNfPChA9rASASdHr.jpg 2x"
alt="Hitman"
src="https://image.tmdb.org/t/p/w94_and_h141_bestv2/3qlQM9KP1cyvNfPChA9rASASdHr.jpg"
srcset="https://image.tmdb.org/t/p/w94_and_h141_bestv2/3qlQM9KP1cyvNfPChA9rASASdHr.jpg 1x, https://image.tmdb.org/t/p/w188_and_h282_bestv2/3qlQM9KP1cyvNfPChA9rASASdHr.jpg 2x"
data-loaded="true">
</body>
</html>
您可以像这样解析“海报”图像：
import io
from bs4 import BeautifulSoup
with io.open("demo.html", encoding="utf8") as fd:
soup = BeautifulSoup(fd.read(), features="html.parser")
posters = soup.find_all("img", {"class": "lazyloaded"})
for poster in posters:
print(poster["src"])
你得到：
https://image.tmdb.org/t/p/w94_and_h141_bestv2/3qlQM9KP1cyvNfPChA9rASASdHr.jpg
