以下是我想略读的文字：

我的代码：

response = requests.request("GET", url, headers=headers)
soup = BeautifulSoup(response.text, "html.parser")
print(soup.prettify())
t = soup.find("tr")
print(t)

代码出现在相当多的地方，但它总是跟在“某人尝试过…”文本后面，因此您可以尝试以下内容：

from bs4 import BeautifulSoup

soup = BeautifulSoup(html, "html.parser")
stripped_strings = soup.stripped_strings

for text in stripped_strings:
    if "Someone tried to sign up for an Instagram account" in text:
        code = next(stripped_strings)
        print(code)
        break

看看.u字符串生成器。
