Why am I getting this error? AttributeError: 'NoneType' object has no attribute 'attrs'

I am trying to scrape all of the href attributes from the page below:

Problem is I get the first link but I get an error at that point. Can anyone show me how to fix this please? I am still learning about Python.

Many thanks

from requests_html import HTMLSession

s = HTMLSession()

url = 'https://lakesshoweringspaces.com/catalogue-product-filter/page/1'

r = s.get(url)

products = r.html.find('article.contentwrapper section')

for item in products:
  print(item.find('a', first=True).attrs['href'])

To expand on Brian's comment, your code assumes that item.find('a', first=True) will successfully find an element. If it doesn't, that code returns None, and then you're asking for None.attrs['href'] (and None doesn't have an attrs attribute, hence the error message).

If we rewrite your code to actually check the return value of the find method:

from requests_html import HTMLSession

s = HTMLSession()

url = "https://lakesshoweringspaces.com/catalogue-product-filter/page/1"

r = s.get(url)

products = r.html.find("article.contentwrapper section")

for item in products:
    res = item.find("a", first=True)
    if res:
        print(res.attrs["href"])
    else:
        print("no match")

Then we find that it fails to find any a elements in every other loop iteration:

https://.../catalogue_product/alassio/?
no match
https://.../catalogue_product/amare/?
no match
https://.../catalogue_product/ambient/?
no match
https://.../catalogue_product/andora/?
no match
https://.../catalogue_product/antigua/?
no match
https://.../catalogue_product/aruba/?
no match
https://.../catalogue_product/avanza/?
no match
https://.../catalogue_product/barbados/?
no match
https://.../catalogue_product/bergen-bi-fold-door/?
no match
https://.../catalogue_product/framed-bi-fold-door/?
no match
https://.../catalogue_product/semi-frameless-bi-fold-door/?
no match
https://.../catalogue_product/cannes-10mm/?
no match

And that's because your expression article.contentwrapper section is matching both sections with class collection-wrapper-item and sections with class compare_favorites_section, the latter of which contain no a elements.

If you modify your code to be more selective:

from requests_html import HTMLSession

s = HTMLSession()

url = "https://lakesshoweringspaces.com/catalogue-product-filter/page/1"

r = s.get(url)

products = r.html.find("article.contentwrapper section.collection-wrapper-item")

for item in products:
    res = item.find("a", first=True)
    if res:
        print(res.attrs["href"])
    else:
        print("no match")

Then you will reliably find the links. Running the above produces:

https://.../catalogue_product/alassio/?
https://.../catalogue_product/amare/?
https://.../catalogue_product/ambient/?
https://.../catalogue_product/andora/?
https://.../catalogue_product/antigua/?
https://.../catalogue_product/aruba/?
https://.../catalogue_product/avanza/?
https://.../catalogue_product/barbados/?
https://.../catalogue_product/bergen-bi-fold-door/?
https://.../catalogue_product/framed-bi-fold-door/?
https://.../catalogue_product/semi-frameless-bi-fold-door/?
https://.../catalogue_product/cannes-10mm/?
