Fitar da wuraren ƙarshen wakili jere ɗaya na tebur a lokaci ɗaya

Yi nazarin kowane jeren wakili a matsayin raka'a ɗaya. Idan ka shimfiɗa duk td da suka dace a shafin kuma ka haɗa sakamakon bisa ƙayyadadden adadi, adireshin daga jere ɗaya na iya haɗuwa da tashar jere na gaba idan tantanin ya ɓace ko wani tebur ya bayyana.

Ga HTML da aikace-aikacen ya riga ya samu, ana iya nazarin teburin da ginshiƙan farko biyu suka zama adireshin IP da tasha kamar haka:

import ipaddress
from bs4 import BeautifulSoup

soup = BeautifulSoup(html, "html.parser")
table = soup.select_one(table_selector)
if table is None:
    raise ValueError("Expected proxy table was not found")

endpoints = set()
for row in table.select("tbody tr"):
    cells = row.find_all("td", recursive=False)
    if len(cells) < 2:
        continue
    try:
        address = ipaddress.ip_address(cells[0].get_text(strip=True))
        port = int(cells[1].get_text(strip=True))
    except ValueError:
        continue
    if 1 <= port <= 65535:
        endpoints.add((str(address), port))

html da table_selector shigarwar aikace-aikacen ne. Zaɓi mai zaɓe da taswirar ginshiƙai daga ainihin rubutun tushen. Jerin wakilai kyauta tushe ɗaya ne na bayanan wuraren ƙarshe, amma ya kamata a duba jerensa kafin zaɓar wannan taswirar. Babu ID na tebur na tarihi ko da'awar cewa shafi yana ɗauke da rikodin 300 daidai da zai zama tsari mai dorewa.
