I want a program with Python that can download all link page in one websiteand take them to a txt file

Here is a Python program that can download all the link pages in one website and save them to a txt file:

import requests
from bs4 import BeautifulSoup

# set the URL of the website to be scraped
url = "https://example.com"

# send a request to the URL and get the HTML content
response = requests.get(url)
html = response.content

# parse the HTML content with BeautifulSoup
soup = BeautifulSoup(html, "html.parser")

# find all the links in the HTML content
links = soup.find_all("a")

# create an empty list to store the link URLs
link_urls = []

# loop through the links and extract their URLs
for link in links:
    link_url = link.get("href")
    if link_url.startswith("http") or link_url.startswith("www"):
        link_urls.append(link_url)

# create a new file called "links.txt" and write the link URLs to it
with open("links.txt", "w") as f:
    for link_url in link_urls:
        f.write(link_url + "\n")

print("All link pages downloaded and saved to links.txt")

This program uses the requests library to send a request to the website and get the HTML content, then uses the BeautifulSoup library to parse the HTML content and find all the links. It then extracts the URLs of the links and stores them in a list. Finally, it creates a new file called "links.txt" and writes the link URLs to it.
