Python - not able to extract value of hidden input

I am trying to extract the value of a hidden input tag. Even though the element exists in the HTML i can't find it with bs4.

This is the error message i get:

AttributeError: 'NoneType' object has no attribute 'find'

This is the html on the webpage:

<form id="exampleid" class="exampleclass" action="/ex/ex-ex/ex/2" method="post">
    
    <more html>
                                
    <div>
    <input type="hidden" name="csrf" value="abcdefghijklmnopqrstuvwxyz">
    </div></form>

And this is my current code:

csrf = soup.find("form", {"id": "exampleid"})
csrf = csrf.find('input', {'name': 'csrf'}).get("value")
print(csrf)

I would appreciate any kind of help as it is really bothering me. Thank you in advance!

Your selection is still working, think there is another issue, maybe you wont get the html you expect.

As alternativ to select and get the value of this hidden <input> you can use the following css selector:

soup.select_one('#exampleid input[name*="csrf"]')['value']

Example

from bs4 import BeautifulSoup

html = '''
<form id="exampleid" class="exampleclass" action="/ex/ex-ex/ex/2" method="post">
<div>
<input type="hidden" name="csrf" value="abcdefghijklmnopqrstuvwxyz">
</div></form>'''

soup = BeautifulSoup(html, "lxml")

csrf = soup.select_one('#exampleid input[name*="csrf"]')['value']

print(csrf)

Output

abcdefghijklmnopqrstuvwxyz
