import requests
from bs4 import BeautifulSoup
import csv
from datetime import datetime  
r = requests.get('http://www.amazon.in/s/ref=nb_sb_noss_2?url=search-alias%3Daps&field-keywords=hp+laptops')
from bs4 import BeautifulSoup  
soup = BeautifulSoup(r.text, 'html.parser')  
results = soup.find_all('ul', attrs={'class':'class="s-result-list s-col-1 s-col-ws-1 s-result-list-hgrid s-height-equalized s-list-view s-text-condensed s-item-container-height-auto"'})
records = []  
for result in results:  
    name = result.findAll('h2', attrs={'class':'a-size-medium s-inline  s-access-title  a-text-normal'}).text # result not results
    price = result.findAll('span', attrs={'class':'a-size-base a-color-price s-price a-text-bold'}).text[13:-11]
    records.append((name, price,))

with open('indd.xls', 'a') as csv_file:
    writer = csv.writer(csv_file)
