How can I loop scraping data for multiple pages in a website using python and beautifulsoup4

Question

I am trying to scrape data from the PGA.com website to get a table of all of the golf courses in the United States. In my CSV table I want to include the Name of the golf course ,Address ,Ownership ,Website , Phone number. With this data I would like to geocode it and place into a map and have a local copy on my computer

I utilized Python and Beautiful Soup4 to extract my data. I have reached as far to extract the data and import it into a CSV but I am now having a problem of scraping data from multiple pages on the PGA website. I want to extract ALL THE GOLF COURSES but my script is limited only to one page I want to loop it in away that it will capture all data for golf courses from all pages found in the PGA site. There are about 18000 gold courses and 900 pages to capture data

Attached below is my script. I need help on creating code that will capture ALL data from the PGA website and not just one site but multiple. In this manner it will provide me with all the data of gold courses in the United States.

Here is my script below:

import csv
import requests 
from bs4 import BeautifulSoup
url = "http://www.pga.com/golf-courses/search?searchbox=Course+Name&searchbox_zip=ZIP&distance=50&price_range=0&course_type=both&has_events=0"

r = requests.get(url)

soup = BeautifulSoup(r.content)

g_data1=soup.find_all("div",{"class":"views-field-nothing-1"})
g_data2=soup.find_all("div",{"class":"views-field-nothing"})

courses_list=[]

for item in g_data2:
     try:
          name=item.contents[1].find_all("div",{"class":"views-field-title"})[0].text
     except:
          name=''
     try:
          address1=item.contents[1].find_all("div",{"class":"views-field-address"})[0].text
     except:
          address1=''
     try:
          address2=item.contents[1].find_all("div",{"class":"views-field-city-state-zip"})[0].text
     except:
          address2=''
     try:
          website=item.contents[1].find_all("div",{"class":"views-field-website"})[0].text
     except:
          website=''   
     try:
          Phonenumber=item.contents[1].find_all("div",{"class":"views-field-work-phone"})[0].text
     except:
          Phonenumber=''      

     course=[name,address1,address2,website,Phonenumber]
     courses_list.append(course)

     with open ('filename5.csv','wb') as file:
          writer=csv.writer(file)
          for row in courses_list:
               writer.writerow(row)    

#for item in g_data1:
     #try:
          #print item.contents[1].find_all("div",{"class":"views-field-counter"})[0].text
     #except:
          #pass  
     #try:
          #print item.contents[1].find_all("div",{"class":"views-field-course-type"})[0].text
     #except:
          #pass

#for item in g_data2:
   #try:
      #print item.contents[1].find_all("div",{"class":"views-field-title"})[0].text
   #except:
      #pass
   #try:
      #print item.contents[1].find_all("div",{"class":"views-field-address"})[0].text
   #except:
      #pass
   #try:
      #print item.contents[1].find_all("div",{"class":"views-field-city-state-zip"})[0].text
   #except:
      #pass

This script only captures 20 at a time and I want to capture all in one script which account for 18000 golf courses and 900 pages to scrape form.

Answer 1

The PGA website's search have multiple pages, the url follows the pattern:

http://www.pga.com/golf-courses/search?page=1 # Additional info after page parameter here

this means you can read the content of the page, then change the value of page by 1, and read the the next page.... and so on.

import csv
import requests 
from bs4 import BeautifulSoup
for i in range(907):      # Number of pages plus one 
    url = "http://www.pga.com/golf-courses/search?page={}&searchbox=Course+Name&searchbox_zip=ZIP&distance=50&price_range=0&course_type=both&has_events=0".format(i)
    r = requests.get(url)
    soup = BeautifulSoup(r.content)

    # Your code for each individual page here 

Answer 2

if you still read this post , you can try this code too....

from urllib.request import urlopen
from bs4 import BeautifulSoup

file = "Details.csv"
f = open(file, "w")
Headers = "Name,Address,City,Phone,Website\n"
f.write(Headers)
for page in range(1,5):
    url = "http://www.pga.com/golf-courses/search?page={}&searchbox=Course%20Name&searchbox_zip=ZIP&distance=50&price_range=0&course_type=both&has_events=0".format(page)
    html = urlopen(url)
    soup = BeautifulSoup(html,"html.parser")
    Title = soup.find_all("div", {"class":"views-field-nothing"})
    for i in Title:
        try:
            name = i.find("div", {"class":"views-field-title"}).get_text()
            address = i.find("div", {"class":"views-field-address"}).get_text()
            city = i.find("div", {"class":"views-field-city-state-zip"}).get_text()
            phone = i.find("div", {"class":"views-field-work-phone"}).get_text()
            website = i.find("div", {"class":"views-field-website"}).get_text()
            print(name, address, city, phone, website)
            f.write("{}".format(name).replace(",","|")+ ",{}".format(address)+ ",{}".format(city).replace(",", " ")+ ",{}".format(phone) + ",{}".format(website) + "\n")
        except: AttributeError
f.close()

where it is written range(1,5) just change that with 0,to the last page , and you will get all details in CSV, i tried very hard to get your data in proper format but it's hard:).

You're putting a link to a single page, it's not going to iterate through each one on its own.

Page 1:

url = "http://www.pga.com/golf-courses/search?searchbox=Course+Name&searchbox_zip=ZIP&distance=50&price_range=0&course_type=both&has_events=0"

Page 2:

http://www.pga.com/golf-courses/search?page=1&searchbox=Course%20Name&searchbox_zip=ZIP&distance=50&price_range=0&course_type=both&has_events=0

Page 907: http://www.pga.com/golf-courses/search?page=906&searchbox=Course%20Name&searchbox_zip=ZIP&distance=50&price_range=0&course_type=both&has_events=0

Since you're running for page 1 you'll only get 20. You'll need to create a loop that'll run through each page.

You can start off by creating a function that does one page then iterate that function.

Right after the search? in the url, starting at page 2, page=1 begins increasing until page 907 where it's page=906.
