I wrote simple code which scrape data from website but i'm struggling to save all rows to csv file. Finished script save only one row - it's last occurance in loop.
def get_single_item_data(item_url):
f= csv.writer(open("scrpe.csv", "wb"))
f.writerow(["Title", "Company", "Price_netto"])
source_code = requests.get(item_url)
soup = BeautifulSoup(source_code.content, "html.parser")
for item_name in soup.find_all('div', attrs={"id" :'main-container'}):
title = item_name.find('h1').text
prodDesc_class = item_name.find('div', class_='productDesc')
company = prodDesc_class.find('p').text
company = company.strip()
price_netto = item_name.find('div', class_="netto").text
price_netto = price_netto.strip()
#print title, company, ,price_netto
f.writerow([title.encode("utf-8"), company, price_netto, ])
Important is to save data to concurrent columns
@PadraicCunningham This is my whole script:
import requests
from bs4 import BeautifulSoup
import csv
url_klocki = "http://selgros24.pl/Dla-dzieci/Zabawki/Klocki-pc1121.html"
r = requests.get(url_klocki)
soup = BeautifulSoup(r.content, "html.parser")
def main_spider(max_page):
page = 1
while page <= max_page:
url = "http://selgros24.pl/Dla-dzieci/Zabawki/Klocki-pc1121.html"
source_code = requests.get(url)
soup = BeautifulSoup(source_code.content, "html.parser")
for link in soup.find_all('article', class_='small-product'):
url = "http://www.selgros24.pl"
a = link.findAll('a')[0].get('href')
href = url + a
#print href
get_single_item_data(href)
page +=1
def get_single_item_data(item_url):
f= csv.writer(open("scrpe.csv", "wb"))
f.writerow(["Title", "Comapny", "Price_netto"])
source_code = requests.get(item_url)
soup = BeautifulSoup(source_code.content, "html.parser")
for item_name in soup.find_all('div', attrs={"id" :'main-container'}):
title = item_name.find('h1').text
prodDesc_class = item_name.find('div', class_='productDesc')
company = prodDesc_class.find('p').text
company = company.strip()
price_netto = item_name.find('div', class_="netto").text
price_netto = price_netto.strip()
print title, company, price_netto
f.writerow([title.encode("utf-8"), company, price_netto])
main_spider(1)
The problem is that you are opening the output file in get_single_item_data
, and it is getting closed when that function returns and f
goes out of scope. You want to pass an open file in to get_single_item_data
so multiple rows will be written.
