Just a quick example of how to use Beautiful Soup

elementarscraper.py

import requests
from bs4 import BeautifulSoup

url = 'http://www.someurl.com.br/products'
headers = {
    'user-agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/53.0.2785.143 Safari/537.36'
}

r = requests.get(url, headers=headers, timeout=5)

# make sure that the page exist
if r.status_code == 200:
    html = r.text
    soup = BeautifulSoup(html, 'lxml')
    # get all products
    products_list_item = soup.find('div', {'class': 'row', 'id': 'products'})
