web scraping using beautiful soup - python

I'm using beautiful soup to scrape a site.
Code:
from bs4 import BeautifulSoup as soup
from urllib.request import urlopen as uReq
my_url = 'https://www.bewakoof.com/biker-t-shirts'
uClient = uReq(my_url)
page_html = uClient.read()
uClient.close()
page_soup = soup(page_html, "html.parser")
containers = page_soup.findAll("div", {"class": "productGrid"})
print(len(containers))
I am getting below mentioned error.
Error
o = containerClass(current_data)
TypeError: __init__() takes 1 positional argument but 2 were given

When I tryed to run part of yours code I've catch an error:
After that i've try to use requests:
>>> my_url = 'https://www.bewakoof.com/biker-t-shirts'
>>> import requests as re
>>> r = re.get(my_url)
>>> r
<Response [403]>
You have got code 403 - it means that the server understood the request but refuses to authorize it. You can get more information about that here
Most often, this error is associated with primitive protection from parsers. To solve this, use this method: You must use headers to deceive the site that you are a browser
To do this download requests lib
then create a dict
headers = {"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.97 Safari/537.36"}
Instead of these values you can substitute your own. The easiest way to do this is with Network Analiser in your browser (press F12 in Chrome)
Then
import requests as req
url = "url"
headers = {"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.97 Safari/537.36"}
r = req.get(url, headers)
But in this situation, the problem is different. The site you are trying to access simply does not work:

Element is not in response Python Requests

I would to scrape the last odds in archive from this page https://www.betexplorer.com/soccer/estonia/esiliiga/elva-flora-tallinn/Q9KlbwaJ/ but I can't get it with requests. How can I get it without interact with Selenium?
To trigger the archive odds page in the Developer Tools I need to hover on the odd.
Code
url = "https://www.betexplorer.com/archive-odds/4l4ubxv464x0xc78lr/14/"
headers = {
"Referer": "https://www.betexplorer.com",
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/92.0.4515.107 Safari/537.36'
}
Json = requests.get(url, headers=headers).json()
As the site is being loaded by JavaScript, requests doesn't work. I have used selenium to load the page, extract the complete source code after everything is loaded.
Then used beautifulsoup to create a soup object to get required data.
From the source code you can see that the data-bid of the <tr> are what are being passed to get the odds data.
I extracted all the data-bid and passed them to the URL you've provided at the very end of your question one by one.
This code will get all the odds data in JSON format
import time
from bs4 import BeautifulSoup
import requests
from selenium import webdriver
base_url = 'https://www.betexplorer.com/soccer/estonia/esiliiga/elva-flora-tallinn/Q9KlbwaJ/'
driver = webdriver.Chrome()
driver.get(base_url)
time.sleep(5)
soup = BeautifulSoup(driver.page_source, 'html.parser')
t = soup.find('table', attrs= {'id': 'sortable-1'})
trs = t.find('tbody').findAll('tr')
for i in trs:
data_bid = i['data-bid']
url = f"https://www.betexplorer.com/archive-odds/4l4ubxv464x0xc78lr/{data_bid}/"
headers = {"Referer": "https://www.betexplorer.com",'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/92.0.4515.107 Safari/537.36'}
Json = requests.get(url, headers=headers).json()
# Do what you wish to do withe JSON data here....

request returns 403 in python beautifulsoup

I am using beautiful soup to try to parse information from a webpage:
url='https://www.onthemarket.com/for-sale/2-bed-flats-apartments/shortlands-station/?max-bedrooms=&radius=0.5'
req=requests.get(url)
req returns <Response [403]>
Python requests. 403 Forbidden suggests there is a user-agent issue, but I cannot find it in my instance.
Are there any suggestions
In such case so please use headers which include user-agent
from bs4 import BeautifulSoup
import requests
url = 'https://www.onthemarket.com/for-sale/2-bed-flats-apartments/shortlands-station/?max-bedrooms=&radius=0.5'
headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.84 Safari/537.36',
'accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8',
}
html_page = requests.get(url, headers=headers).text
soup = BeautifulSoup(html_page, "html.parser")
print(soup.text)

How to do scraping from a page with BeautifulSoup

The question asked is very simple, but for me, it doesn't work and I don't know!
I want to scrape the rating beer from this page https://www.brewersfriend.com/homebrew/recipe/view/16367/southern-tier-pumking-clone with BeautifulSoup, but it doesn't work.
This is my code:
import requests
import bs4
from bs4 import BeautifulSoup
url = 'https://www.brewersfriend.com/homebrew/recipe/view/16367/southern-tier-pumking-clone'
test_html = requests.get(url).text
soup = BeautifulSoup(test_html, "lxml")
rating = soup.findAll("span", class_="ratingValue")
rating
When I finish, it doesn't work, but if I do the same thing with another page is work... I don't know. Someone can help me? The result of rating is 4.58
Thanks everybody!
If you print the test_html, you'll find you get a 403 forbidden response.
You should add a header (at least a user-agent : ) ) to your GET request.
import requests
from bs4 import BeautifulSoup
headers = {
'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3729.108 Safari/537.36'
}
url = 'https://www.brewersfriend.com/homebrew/recipe/view/16367/southern-tier-pumking-clone'
test_html = requests.get(url, headers=headers).text
soup = BeautifulSoup(test_html, 'html5lib')
rating = soup.find('span', {'itemprop': 'ratingValue'})
print(rating.text)
# 4.58
The reason behind getting forbidden status code (HTTP error 403) which means the server will not fulfill your request despite understanding the response. You will definitely get this error if you try scrape a lot of the more popular websites which will have security features to prevent bots. So you need to disguise your request!
For that you need use Headers.
Also you need correct your tag attribute whose data you're trying to get i.e. itemprop
use lxml as your tree builder, or any other of your choice
import requests
from bs4 import BeautifulSoup
url = 'https://www.brewersfriend.com/homebrew/recipe/view/16367/southern-tier-pumking-clone'
# Add this
headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.86 Safari/537.36'}
test_html = requests.get(url, headers=headers).text
soup = BeautifulSoup(test_html, 'lxml')
rating = soup.find('span', {'itemprop':'ratingValue'})
print(rating.text)
The page you are requesting response as 403 forbidden so you might not be getting an error but it will provide you blank result as []. To avoid this situation we add user agent and this code will get you the desired result.
import urllib.request
from bs4 import BeautifulSoup
user_agent = 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.7) Gecko/2009021910 Firefox/3.0.7'
url = "https://www.brewersfriend.com/homebrew/recipe/view/16367/southern-tier-pumking-clone"
headers={'User-Agent':user_agent}
request=urllib.request.Request(url,None,headers) #The assembled request
response = urllib.request.urlopen(request)
soup = BeautifulSoup(response, "lxml")
rating = soup.find('span', {'itemprop':'ratingValue'})
rating.text
import requests
from bs4 import BeautifulSoup
headers = {
'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64)
AppleWebKit/537.36
(KHTML, like Gecko) Chrome/74.0.3729.108 Safari/537.36'
}
url = 'https://www.brewersfriend.com/homebrew/recipe/view/16367/southerntier-pumking
clone'
test_html = requests.get(url, headers=headers).text
soup = BeautifulSoup(test_html, 'html5lib')
rating = soup.find('span', {'itemprop': 'ratingValue'})
print(rating.text)
you are facing this error because some websites can't be scraped by beautiful soup. So for these kinds of websites, you have to use selenium
download latest chrome driver from this link according to your operating system
install selenium driver by this command "pip install selenium"
# import required modules
import selenium
from selenium import webdriver
from bs4 import BeautifulSoup
import time, os
curren_dir = os.getcwd()
print(curren_dir)
# concatinate web driver with your current dir && if you are using window change "/" to '\' .
# make sure , you placed chromedriver in current directory
driver = webdriver.Chrome(curren_dir+'/chromedriver')
# driver.get open url on your browser
driver.get('https://www.brewersfriend.com/homebrew/recipe/view/16367/southern-tier-pumking-clone')
time.sleep(1)
# it fetch data html data from driver
super_html = driver.page_source
# now convert raw data with 'html.parser'
soup=BeautifulSoup(super_html,"html.parser")
rating = soup.findAll("span",itemprop="ratingValue")
rating[0].text

How to crawl website slower in Python with Jupyter Notebook?

My current python script would perform web scraping on the website in one second with 2 pages. I want to make it go slower, like 25 seconds on one page. How do I do that?
I tried this following python script.
# Dependencies
from bs4 import BeautifulSoup
import requests
import pandas as pd
# Testing
linked = 'https://www.zillow.com/homes/for_sale/San-Francisco-CA/fsba,fsbo,fore,new_lt/house_type/20330_rid/globalrelevanceex_sort/37.859675,-122.285557,37.690612,-122.580815_rect/11_zm/{}_p/0_mmm/'
for link in [linked.format(page) for page in range(1,2)]:
user_agent = 'Mozilla/5.0 (Windows NT 6.3; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.113 Safari/537.36'
headers = {'User-Agent': user_agent}
response = requests.get(link, headers=headers)
soup = BeautifulSoup(response.text, 'html.pafinite-item')
print(soup)
What should I add to my script to make the web scraping go slower?
Just use time.sleep:
import requests
import pandas as pd
from time import sleep
from bs4 import BeautifulSoup
linked = 'https://www.zillow.com/homes/for_sale/San-Francisco-CA/fsba,fsbo,fore,new_lt/house_type/20330_rid/globalrelevanceex_sort/37.859675,-122.285557,37.690612,-122.580815_rect/11_zm/{}_p/0_mmm/'
for link in [linked.format(page) for page in range(1,2)]:
sleep(25.0)
user_agent = 'Mozilla/5.0 (Windows NT 6.3; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.113 Safari/537.36'
headers = {'User-Agent': user_agent}
response = requests.get(link, headers=headers)
soup = BeautifulSoup(response.text, 'html.pafinite-item')
print(soup)

Basic Python Scraper with TypeError: object of type 'Response' has no len()

I'm new to coding a webscraper with Python. I've done a few tutorials and now I am trying my first one. A really simple test here that yields the error I noted in the Subject line.
import requests
from bs4 import BeautifulSoup
url = "https://www.autotrader.ca/cars/mercedes-benz/ab/calgary/?rcp=15&rcs=0&srt=3&prx=100&prv=Alberta&loc=T3P%200H2&hprc=True&wcp=True&sts=Used&adtype=Private&showcpo=1&inMarket=advancedSearch"
user_agent = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3578.98 Safari/537.36'
html = requests.get(url,headers={'User-Agent': user_agent})
soup = BeautifulSoup(html, "lxml")
print(soup)
Please help me out with trying out this code. Any help is greatly appreciated!
Use html.text instead of html. It's a good practice to send the headers binded with user-agent inside the get() method.
import requests
from bs4 import BeautifulSoup
url = "https://www.autotrader.ca/cars/mercedes-benz/ab/calgary/?rcp=15&rcs=0&srt=3&prx=100&prv=Alberta&loc=T3P%200H2&hprc=True&wcp=True&sts=Used&adtype=Private&showcpo=1&inMarket=advancedSearch"
headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.113 Safari/537.36'}
response = requests.get(url,headers=headers)
soup = BeautifulSoup(response.text,"lxml")
return soup
Make changes in this line:
soup = BeautifulSoup(html, "lxml")
to
soup = BeautifulSoup(html.content, "lxml")
or
soup = BeautifulSoup(html.text, "lxml")
This returns the HTML structure of the webpage.
