I wrote a scraper with rotating proxies

Code:
import requests, re

from bs4 import BeautifulSoup



regex = r"[0-9]+(?:\.[0-9]+){3}:[0-9]+"

c = requests.get("https://spys.me/proxy.txt")

test_str = c.text

a = re.finditer(regex, test_str, re.MULTILINE)

with open("proxies_list.txt", 'w') as file:

    for i in a:

       print(i.group(),file=file)



d = requests.get("https://free-proxy-list.net/")

soup = BeautifulSoup(d.content, 'html.parser')

td_elements = soup.select('.fpl-list .table tbody tr td')

ips = []

ports = []

for j in range(0, len(td_elements), 8):

    ips.append(td_elements[j].text.strip())

    ports.append(td_elements[j + 1].text.strip())

with open("proxies_list.txt", "a") as myfile:

    for ip, port in zip(ips, ports):

        proxy = f"{ip}:{port}"

        print(proxy, file=myfile)



allprox = open("proxies_list.txt","r").readlines()

proxies = {}

for p in allprox:

    try:

        (ip, port) = p.split(":")

        proxies["http://" + ip] = "http://" + ip + ":" + port

        proxies["https://" + ip] = "https://" + ip + ":" + port

    except:

        pass



urls = ["https://www.gorzek.com","http://www.sendersilent.com","https://hosting.gorzek.com","http://navi.gorzek.com"]



for u in urls:

    response = requests.get(u, proxies=proxies)

    print(response.content)
