How to scrape href using bs4 and Python - python-3.x

I am trying to scrape the "href" links from the page, but the result is "none", can you please help me find where my code is going wrong? why is the code returning "none"?
import requests
from bs4 import BeautifulSoup
import pprint
res = requests.get('https://news.ycombinator.com/newest')
soup = BeautifulSoup(res.text, 'html.parser')
links = soup.select('.titleline')
def fit_hn(links):
hn = []
for idx, item in enumerate(links):
href = links[idx].get('href')
hn.append(href)
return hn
pprint.pprint(fit_hn(links))

Let's take a deeper look.
if you were to print links, you'll see that it's returning the span with the a:
<span class="titleline">The Strangely Beautiful Experience of Google Reviews<span class="sitebit comhead"> (<span class="sitestr">longreads.com</span>)</span></span>
So, really you need to go one level deeper and select the <a> tag.
Change your CSS selector to also select the a tags:
links = soup.select('.titleline a')
Your above code now prints:
['https://www.the-sun.com/tech/7078358/xoxe-ai-woman-detects-anxiety-and-crime-afterlife/',
'from?site=the-sun.com',

Beautiful Soup Nested Loops

I was hoping to create a list of all of the firms featured on this list. I was hoping each winner would be their own section in the HTML but it looks like there are multiple grouped together across several divs. How would you recommend going about solving this? I was able to pull all of the divs but i dont know how to cycle through them appropriately. Thanks!
import requests
from bs4 import BeautifulSoup
import csv
request = requests.get("https://growthcapadvisory.com/growthcaps-top-40-under-40-growth-investors-of-2020/")
text = request.text
soup = BeautifulSoup(text, 'html.parser')
element = soup.find()
person = soup.find_all('div', class_="under40")
This solution uses css selectors
import requests
from bs4 import BeautifulSoup
request = requests.get("https://growthcapadvisory.com/growthcaps-top-40-under-40-growth-investors-of-2020/")
text = request.text
soup = BeautifulSoup(text, 'html.parser')
# if you have an older version you'll need to use contains instead of -soup-contains
firm_tags = soup.select('h5:-soup-contains("Firm") strong')
# extract the text from the selected bs4.Tags
firms = [tag.text for tag in firm_tags]
# if there is extra whitespace
clean_firms = [f.strip() for f in firms]
It works by selecting all the strong tags whose parent h5 tag contain the word "Firm"

How can I scrape a <h1> tag using BeautifulSoup? [Python]

I am currently coding a price tracker for different websites, but I have run into an issue.
I'm trying to scrape the contents of a h1 tag using BeautifulSoup4, but I don't know how. I've tried to use a dictionary, as suggested in
https://stackoverflow.com/a/40716482/14003061, but it returned None.
Can someone please help? It would be appreciated!
Here's the code:
from termcolor import colored
import requests
from bs4 import BeautifulSoup
import smtplib
def choice_bwfo():
print(colored("You have selected Buy Whole Foods Online [BWFO]", "blue"))
url = input(colored("\n[ 2 ] Paste a product link from BWFO.\n", "magenta"))
url_verify = requests.get(url, headers=headers)
soup = BeautifulSoup(url_verify.content, 'html5lib')
item_block = BeautifulSoup.find('h1', {'itemprop' : 'name'})
print(item_block)
choice_bwfo()
here's an example URL you can use:
https://www.buywholefoodsonline.co.uk/organic-spanish-bee-pollen-250g.html
Thanks :)
This script will print content of <h1> tag:
import requests
from bs4 import BeautifulSoup
url = 'https://www.buywholefoodsonline.co.uk/organic-spanish-bee-pollen-250g.html'
# create `soup` variable from the URL:
soup = BeautifulSoup(requests.get(url).content, 'html.parser')
# print text of first `<h1>` tag:
print(soup.h1.get_text())
Prints:
Organic Spanish Bee Pollen 250g
Or you can do:
print(soup.find('h1', {'itemprop' : 'name'}).get_text())

can't scape a value from Beautifulsoup in python

I am creating a website where I display the current wind. when I go to https://www.windguru.cz/station/219 (and click on inspect element at the max:{wind}) I can see this:
<span class="wgs_wind_max_value">12</span>
the 12 is the value I need but when I try to scrape it with bs4 and requests, this appears as output:
<span class="wgs_wind_max_value"></span>
as you can see there is no '12' value.
can someone help me with that?
from bs4 import BeautifulSoup
import requests
page = requests.get('https://www.windguru.cz/3323')
soup = BeautifulSoup(page.content, "lxml")
table = soup.find_all("span",{"class","wgs_wind_max_value"})
print(table)
Use the same API as page does to get json to populate those values. Notice the querystring construction passed to the API.
import requests
headers = {'Referer' : 'https://www.windguru.cz/station/219'}
r = requests.get('https://www.windguru.cz/int/iapi.php?q=station_data_current&id_station=219&date_format=Y-m-d%20H%3Ai%3As%20T&_mha=f4d18b6c', headers = headers).json()
print(r)
print(r['wind_max'])

Parsing through HTML with BeautifulSoup in Python

Currently my code is as follows:
from bs4 import BeautifulSoup
import requests
main_url = 'http://www.foodnetwork.com/recipes/a-z'
response = requests.get(main_url)
soup = BeautifulSoup(response.text, "html.parser")
mylist = [t for tags in soup.find_all(class_='m-PromoList o-Capsule__m-
PromoList') for t in tags if (t!='\n')]
As of now, I get a list containing the correct information but its still inside of HTML tags. An example of an element of the list is given below:
<li class="m-PromoList__a-ListItem">"16 Bean" Pasta E Fagioli</li>
from this item I want to extract both the href link and also the following string separately, but I am having trouble doing this and I really don't think getting this info should require a whole new set of operations. How do?
You can do this to get href and text for one element:
href = soup.find('li', attrs={'class':'m-PromoList__a-ListItem'}).find('a')['href']
text = soup.find('li', attrs={'class':'m-PromoList__a-ListItem'}).find('a').text
For a list of items:
my_list = soup.find_all('li', attrs={'class':'m-PromoList__a-ListItem'})
for el in my_list:
href = el.find('a')['href']
text = el.find('a').text
print(href)
print(text)
Edit:
An important tip to reduce run time: Don't search for the same tag more than once. Instead, save the tag in a variable and then use it multiple times.
a = soup.find('li', attrs={'class':'m-PromoList__a-ListItem'}).find('a')
href = a.get('href')
text = a.text
In large HTML codes, finding a tag takes up lot of time, so doing this will reduce the time taken to find the tag as it will run only once.
Several ways you can achieve the same. Here is another approach using css selector:
from bs4 import BeautifulSoup
import requests
response = requests.get('http://www.foodnetwork.com/recipes/a-z')
soup = BeautifulSoup(response.text, "lxml")
for item in soup.select(".m-PromoList__a-ListItem a"):
print("Item_Title: {}\nItem_Link: {}\n".format(item.text,item['href']))
Partial result:
Item_Title: "16 Bean" Pasta E Fagioli
Item_Link: //www.foodnetwork.com/recipes/ina-garten/16-bean-pasta-e-fagioli-3612570
Item_Title: "16 Bean" Pasta e Fagioli
Item_Link: //www.foodnetwork.com/recipes/ina-garten/16-bean-pasta-e-fagioli-1-3753755
Item_Title: "21" Apple Pie
Item_Link: //www.foodnetwork.com/recipes/21-apple-pie-recipe-1925900

Web Crawler keeps saying no attribute even though it really has

I have been developing a web-crawler for this website (http://www.bobaedream.co.kr/cyber/CyberCar.php?gubun=I&page=1). But I have a trouble at crawling each title of the stock. I am pretty sure that there is attribute for carinfo_title = carinfo.find_all('a', class_='title').
Please check out the attached code and website code, and then give me any advice.
Thanks.
(Website Code)
https://drive.google.com/open?id=0BxKswko3bYpuRV9seTZZT3REak0
(My code)
from bs4 import BeautifulSoup
import urllib.request
target_url = "http://www.bobaedream.co.kr/cyber/CyberCar.php?gubun=I&page=1"
def fetch_post_list():
URL = target_url
res = urllib.request.urlopen(URL)
html = res.read()
soup = BeautifulSoup(html, 'html.parser')
table = soup.find('table', class_='cyber')
#Car Info and Link
carinfo = table.find_all('td', class_='carinfo')
carinfo_title = carinfo.find_all('a', class_='title')
print (carinfo_title)
return carinfo_title
fetch_post_list()
You have multiple elements with the carinfo class and for every "carinfo" you need to get to the car title. Loop over the result of the table.find_all('td', class_='carinfo'):
for carinfo in table.find_all('td', class_='carinfo'):
carinfo_title = carinfo.find('a', class_='title')
print(carinfo_title.get_text())
Would print:
미니 쿠퍼 S JCW
지프 랭글러 3.8 애니버서리 70주년 에디션
...
벤츠 뉴 SLK200 블루이피션시
포르쉐 뉴 카이엔 4.8 GTS
마쯔다 MPV 2.3
Note that if you need only car titles, you can simplify it down to a single line:
print([elm.get_text() for elm in soup.select('table.cyber td.carinfo a.title')])
where the string inside the .select() method is a CSS selector.
