[Python] How to enable cookie with Python requests?

I want to sign in Amazon.com with Python. But I can't do it even if I use requests.Session() , because I can't "Enable Cookies".

Could you tell me how to fix the code? Why "dict(response.cookies)" return empty?

# creating all input tag information (hidden tags are included)
# {'pageId': 'ape:dXNmbGV....'email': 'xxx@xxx', 'password': 'xxx', 'create': '0'}
def create_signin_data(res, user, pass) -> str:
bs = BeautifulSoup(res.content, "html.parser")
signin_data = {s["name"]: s["value"]
for s in bs.select("form[name=signIn]")[0].select("input[name]")
if s.has_attr("value")}
signin_data[u"email"] = user
signin_data[u"password"] = pass
return signin_data

signin_url ="https://www.amazon.com/ap/signin?_encoding=UTF8&........."
action_url ="https://www.amazon.com/ap/signin"

### create session
session = requests.Session()
res = session.get(signin_url)
# res = session.get(signin_url, cookies = res.cookies) -> the result is the same
cookie_data = dict(response.cookies) # empty dict {}

### sign in
signin_data = create_signin_data(res, "user@addr", "pass")
res = session.post(signin_url, signin_data)
# res = session.post(action_url, signin_data) -> the result is the same
# res = session.post(signin_url, signin_data, cookies=cookie_data ) -> the result is the same

print(res.content)
