Beautiful Soup saving sessions to checkout products - python-3.x

Question

I am trying to write a bot to add items to my cart then purchase them for me because I need to make very regular purchases and it becomes tedious to purchase them myself.
from bs4 import BeautifulSoup
import requests
import numpy as np
page = requests.get("http://www.onlinestore.com/shop")
soup = BeautifulSoup(page.content, 'html.parser')
try:
for i in soup.find_all('a'):
if "shop" in i['href']:
shop_page = requests.get("http://www.onlinestore.com" + i['href'])
item_page = BeautifulSoup(shop_page.content, 'html.parser')
for h in item_page.find_all('form', class_="add"):
print(h['action'])
try:
shop_page = requests.get("http://www.online.com" + h['action'])
except:
print("None left")
for h in item_page.find_all('h1', class_="protect"):
print(h.getText())
except:
print("either ended or error occured")
checkout_page = requests.get("http://www.onlinestore.com/checkout")
checkout = BeautifulSoup(checkout_page.content, 'html.parser')
for j in checkout.find_all('strong', id_="total"):
print(j)
I was having some trouble checking out the products because the items don't carry over. Is there a way that I can implement cookies so that it keeps track my items I have added to cart?
Thanks

Even though requests is not a browser, it still can persist headers and cookies across multiple requests, but if you use a Session:
with requests.Session() as session:
page = session.get("http://www.onlinestore.com/shop")
# use "session" instead of "requests" later on
Note that you would also get a performance boost for free because of the persistent connection:
if you're making several requests to the same host, the underlying TCP
connection will be reused, which can result in a significant
performance increase
Depending on how the cart and checkout on this specific online store are implemented this may or may not work. But, at least, this is a step forward.
