如何在bs4中选择id，它是一个数字？

from bs4 import BeautifulSoup

# 假设HTML代码如下
html = """
<div id="123">...</div>
"""

soup = BeautifulSoup(html, 'html.parser')

# 通过find()方法选择id为数字的元素
element = soup.find(id="123")
print(element)

<div id="123">...</div>

from bs4 import BeautifulSoup

# 假设HTML代码如下
html = """
<div id="123">...</div>
<div id="456">...</div>
<div id="789">...</div>
"""

soup = BeautifulSoup(html, 'html.parser')

# 通过find_all()方法选择所有id为数字的元素
elements = soup.find_all(id=True)
for element in elements:
    if element.get('id').isdigit():
        print(element)

<div id="123">...</div>
<div id="456">...</div>
<div id="789">...</div>
