Beautiful Soup 4, findAll - web-scraping

Question

My code is this
from urllib.request import urlopen as uReq
from bs4 import BeautifulSoup as soup
my_url=https://www.chembid.com/results/?q=124-07-2&sort=price
my_url='https://www.chembid.com/results/?q=124-07-2&sort=price'
# opening up connection grapping the page
uClient=uReq(my_url)
page_html=uClient.read()
uClient.close()
#html parser
page_soup=soup(page_html,"html.parser")
for Container in Containers:
name=Container.div.div.span
title_container=Container.findAll("a",{"class":"supplier"})
supplier=title_container[0].text
And what im trying to do is now to use bs4 to findAll
>>> cas_no=Container.findAll("span",{"class":"regular-small-regular-small-font block"})
in this code
Factory supply high quality 99% min Octanoic acid/caprylic acid CAS 124-07-2 used in the manufacture of dyes, drugs, spices

And what im trying to find is the name, supplier, Cas-no, quality and price.
Thanks

Answer 1

so first thing I'm seeing is your trying to iterate through your Containers object, but never stored that as anything. So you'll need to have that stored before iterating through that.
hopefully someone will post a more robust solution, but in terms of what is pulled and what you're asking as an output, this will pull it from that specific page. There are a few parts that are not present so I had to account for those and if they weren't there, just have a null. None the less, this should get you going:
from urllib.request import urlopen as uReq
from bs4 import BeautifulSoup as soup
import pandas as pd
results = pd.DataFrame()
my_url='https://www.chembid.com/results/?q=124-07-2&sort=price'
# opening up connection grapping the page
uClient=uReq(my_url)
page_html=uClient.read()
uClient.close()
#html parser
page_soup=soup(page_html,"html.parser")
containers = page_soup.find_all('div', {'class':"result-horizontal-wrapper"})
for container in containers:
name = container.div.div.span.text
if container.find('a' , {'class':'supplier'}):
supplier = container.find('a' , {'class':'supplier'}).text
else:
supplier = 'n/a'
span_cas_qulity = container.find_all('span', {'class':'regular-small-font block'})
cas_no = [x.text for x in span_cas_qulity if 'CAS' in x.text]
quality = [x.text for x in span_cas_qulity if 'Quality/Grade' in x.text]
if cas_no != []:
cas_no = cas_no[0]
else:
cas_no = None
if quality != []:
quality = quality[0]
else:
quality = None
span_price = container.select('span.black-bold-font-big')[0].text
span_rate = container.select('span.block.regular-small-font.price')[0].text
temp_df = pd.DataFrame([[name, supplier, cas_no, quality, span_price, span_rate]], columns = ['name','supplier','cas_no','quality','price','rate'])
results = results.append(temp_df).reset_index(drop = True)
