Scraping python

Can someone tell me why this code is returning the first page for multiple times, please?

import csv

import requests

import datetime

from bs4 import BeautifulSoup   

 

sf = 3


name = "aragaz" + datetime.datetime.now().strftime("%Y-%m-%d-%H-%M")+".csv"

with open(name, "w+") as f:

 

    writer = csv.writer(f)

    writer.writerow(["Date","Inf","Actual"])

    y = 1

   

    while y <= sf:

 

        r = requests.get("https://altex.ro/apa-espresso-cafea/cafetiere/filtru/p/".format(y))

 

        soup = BeautifulSoup(r.text, "html.parser")

        x = soup.find_all("li", {'class': 'Products-item'})

        y += 1

        for Products in x:

            Date = Products.find('h2', {'class': "Product-nameHeading"}).text.strip()

            Inf = Products.find('div', {'class': "Price"}).text.strip()

           

           

            writer.writerow([Date, Inf, datetime.datetime.now()])
