Get the lists of things to do from tripadvisor


how to get the 'things to do' list? I am new to webscraping and i don't know how to loop through each page to get the href of all 'things to do'?tell me where i am doing wrong?Any help would be highly apreciated. Thanks in advance.

import requests
import re
from bs4 import BeautifulSoup
from urllib.request import urlopen



offset = 0
url = 'https://www.tripadvisor.com/Attractions-g255057-Activities-oa' + str(offset) + '-Canberra_Australian_Capital_Territory-Hotels.html#ATTRACTION_LIST_CONTENTS'
urls = []
r = requests.get(url)
soup = BeautifulSoup(r.text, "html.parser")


for link in soup.find_all('a', {'last'}):
    page_number = link.get('data-page-number')
    last_offset = int(page_number) * 30
    print('last offset:', last_offset)


for offset in range(0, last_offset, 30):
    print('--- page offset:', offset, '---')
    url = 'https://www.tripadvisor.com/Attractions-g255057-oa' + str(offset) + '-Canberra_Australian_Capital_Territory-Hotels.html#ATTRACTION_LIST_CONTENTS'
    r = requests.get(url)
    soup = BeautifulSoup(r.text, "html.parser")

    for link in soup.find_all('a', {'property_title'}):
        iurl='https://www.tripadvisor.com/Attraction_Review-g255057' + link.get('href')
        print(iurl)

Basically i want the href of each 'things to do'. My desired output for 'things to do' is:

   https://www.tripadvisor.com/Attraction_Review-g255057-d3377852-Reviews-Weston_Park-Canberra_Australian_Capital_Territory.html
   https://www.tripadvisor.com/Attraction_Review-g255057-d591972-Reviews-Canberra_Museum_and_Gallery-Canberra_Australian_Capital_Territory.html
   https://www.tripadvisor.com/Attraction_Review-g255057-d312426-Reviews-Lanyon_Homestead-Canberra_Australian_Capital_Territory.html
   https://www.tripadvisor.com/Attraction_Review-g255057-d296666-Reviews-Australian_National_University-Canberra_Australian_Capital_Territory.html

Like in below example i used this code for getting the href of each restaurant in canberra city my code for restauranr which works perfectly is:

import requests
import re
from bs4 import BeautifulSoup
from urllib.request import urlopen



with requests.Session() as session:
    for offset in range(0, 1050, 30):
        url = 'https://www.tripadvisor.com/Restaurants-g255057-oa{0}-Canberra_Australian_Capital_Territory.html#EATERY_LIST_CONTENTS'.format(offset)

        soup = BeautifulSoup(session.get(url).content, "html.parser")
        for link in soup.select('a.property_title'):
            iurl = 'https://www.tripadvisor.com/' + link.get('href')
            print(iurl)        

the output of restaurant code is:

   https://www.tripadvisor.com/Restaurant_Review-g255057-d1054676-Reviews-Lanterne_Rooms-Canberra_Australian_Capital_Territory.html
   https://www.tripadvisor.com/Restaurant_Review-g255057-d755055-Reviews-Courgette_Restaurant-Canberra_Australian_Capital_Territory.html
   https://www.tripadvisor.com/Restaurant_Review-g255057-d6893178-Reviews-Pomegranate-Canberra_Australian_Capital_Territory.html

Solution

  • Ok , it's not that hard, you just have to know which tags to use .
    Let me explain with this example :

    import requests
    from bs4 import BeautifulSoup
    
    base_url = 'https://www.tripadvisor.com/'  ## we need this to join the links later ##
    main_page = 'https://www.tripadvisor.com/Attractions-g255057-Activities-oa{}-Canberra_Australian_Capital_Territory-Hotels.html#ATTRACTION_LIST_CONTENTS'
    links = []
    
    ## get the initial page to find the number of pages ##
    r = requests.get(main_page.format(0))  
    soup = BeautifulSoup(r.text, "html.parser")
    ## select the last page from the list of pages ('a', {'class':'pageNum taLnk'}) ##
    last_page = max([ int(page.get('data-offset')) for page in soup.find_all('a', {'class':'pageNum taLnk'}) ])
    
    ## now iterate over that range (first page, last page, number of links), and extract the links from each page ##
    for i in range(0, last_page + 30, 30):
        page = main_page.format(i)
        soup = BeautifulSoup(requests.get(page).text, "html.parser") ## get the next page and parse it with BeautifulSoup ##  
        ## get the hrefs from ('div', {'class':'listing_title'}), and join them with base_url to make the links ##
        links += [ base_url + link.find('a').get('href') for link in soup.find_all('div', {'class':'listing_title'}) ]
    
    for link in links : 
        print(link)
    

    That gives us 8 pages and 212 links in total ( 30 on each page, 2 on the last ) .
    I hope this clears things up a bit
