Duplicates links in python

Question

Good morning world

I'm new to python and trying out things. I'm trying to remove duplicate links from the below run. currently their are 253 links that were retrieved. Can someone please help me with this?

import requests

from bs4 import BeautifulSoup

import csv

page = "https://www.census.gov/programs-surveys/popest.html"

r = requests.get(page)

raw_html = r.text

soup = BeautifulSoup(raw_html, 'html.parser')

links = soup.find_all("a")

print ('Number of links retrieved: ', len (links))

Convert it to a set and it will remove duplicates:

links = set(soup.find_all("a"))

out:
Number of links retrieved:  244

set will not care about the sort order.

Therefor i used a list with cleaning the href correctly.

Now the len is 123

from bs4 import BeautifulSoup
import requests

r = requests.get("https://www.census.gov/programs-surveys/popest.html")
soup = BeautifulSoup(r.text, 'html.parser')

links = []
for item in soup.findAll("a", href=True):
    item = item.get("href")
    if item.startswith("h"):
        pass
    else:
        item = f"https://www.census.gov/{item}"
    if item not in links:
        links.append(item)
        print(item)


print(len(links))

Output:

@riya `comment` section is not for extend or reproduce your `code`. however the `len` without duplicates is `123`. you have to run the code on your end to check the output. — αԋɱҽԃ αмєяιcαη, Mar 12 '20 at 18:05
Thanks. Sorry I was just showing you what I have. I'll try it out. — riya, Mar 12 '20 at 18:09
@riya no worries, I've seen your code on the question which you've asked. and verified your current output. — αԋɱҽԃ αмєяιcαη, Mar 12 '20 at 18:10
I tried it and got the same result and I take it its already in absolute format right? if not, is there anything I need to do to make it that. — riya, Mar 13 '20 at 03:23
