Python 使用BeautifulSoup从<；获取文本；预处理>；要素

我一直在试图从中提取DNA序列，但似乎无法获取数据。我的代码如下所示。如果有什么帮助的话，我也在关注数据抓取，我的代码的开头应该和他们的类似

from urllib.request import urlopen as uReq
from bs4 import BeautifulSoup as bslol

# URl to web scrape from
page_url = 'https://www.ncbi.nlm.nih.gov/nuccore/MT755607.1?report=fasta'

# opens the connection and downloads html page from url
uClient = uReq(page_url)

# parses html into a soup data structure to traverse html
# as if it were a json data type.
page_soup = bslol(uClient.read(), "html.parser")
uClient.close()

为了获取文本，我首先尝试使用

print（page\u soup.select（'pre'））

，它返回空括号

然后我试着做

page_-soup.find（'div'，{'class'：'seq-gbff'}）。text

以及

page_-soup.find（'div'，{'class'：'seq-gbff'}）。content

但没有效果。我还尝试使用

.findAll

查看是否有任何更改，但这并没有让我更接近解决方案

---

如果有人能帮我解决这个问题，我将不胜感激。

实际上，该网站使用JavaScript加载该

代码块

urllib.request

无法加载需要加载JavaScript的内容。使用

selenium

在浏览器（Edge、Firefox或Chrome）中加载页面，然后可以将页面加载到bs4解析器中以解析HTML内容。您也可以仅使用Selenium从网站中获取数据，而不使用bs4解析器

import requests

res = requests.get('https://www.ncbi.nlm.nih.gov/sviewer/viewer.fcgi?id=1877761002&db=nuccore&report=fasta&extrafeat=null&conwithfeat=on&hide-cdd=on&retmode=html&withmarkup=on&tool=portal&log$=seqview&maxdownloadsize=1000000')

dna_sequence = res.text.strip()

print(dna_sequence)

---

前往官方网站-

分析网站时，网站会发出ajax调用以加载dna序列
