retrieve links from web page using python and BeautifulSoup than select 3 link and run it 4 times

Content Index :

it should still fix some issue I was able to accomplish your homework in the following way (please take the time to learn this):
import urllib
from bs4 import BeautifulSoup

# This function will get the Nth link object from the given url.
# To be safe you should make sure the nth link exists (I did not)
def getNthLink(url, n):
    html = urllib.urlopen(url).read()
    soup = BeautifulSoup(html, 'html.parser')
    tags = soup('a')
    return tags[n-1]

url = "https://pr4e.dr-chuck.com/tsugi/mod/python-data/data/known_by_Fikret.html"

# This iterates 4 times, each time grabbing the 3rd link object
# For convenience it prints the url each time.
for i in xrange(4):
    tag = getNthLink(url,3)
    url = tag.get('href')
    print url

# Finally after 4 times we grab the content from the last tag
print tag.contents[0]

This might help you How can I retrieve the links of a webpage and copy the url address of the links using Python? , Here's a short snippet using the SoupStrainer class in BeautifulSoup:
import httplib2
from BeautifulSoup import BeautifulSoup, SoupStrainer

http = httplib2.Http()
status, response = http.request('http://www.nytimes.com')

for link in BeautifulSoup(response, parse_only=SoupStrainer('a')):
    if link.has_attr('href'):

I wish this help you Is it somehow possible to only get lets say the first 10 links from a page with BeautifulSoup? , Would something like this work:
for tag in soupan.findAll('a')[:10]:

I wish this help you There is no need to use BeautifulSoup for this. The site is returning perfectly valid XML that can be parsed with Python's included tools:
import requests
import xml.etree.ElementTree as et

req = requests.get('http://www.agenzia-interinale.it/sitemap-5.xml')
root = et.fromstring(req.content)
for i in root:
    print i[0].text  # the <loc> text

seems to work fine You don't need a nested loop here. Other notes/improvements:
opener.open() result can be passed directly to BeautifulSoup constructor, no need for read() urlopener can be defined once and reused in the loop to follow links use find_all() instead of findAll() use urljoin() for concatenating url parts use csv module for writing the delimited data use with context manager while dealing with files
import csv
import re
import time
import urllib2
from urlparse import urljoin
from bs4 import BeautifulSoup

BASE_URL = 'http://omaha.craigslist.org/sys/'
URL = 'http://omaha.craigslist.org/sya/'
FILENAME = 'C:/Python27/Folder/Folder/Folder/craigstvs.txt'

opener = urllib2.build_opener()
opener.addheaders = [('User-agent', 'Mozilla/5.0')]
soup = BeautifulSoup(opener.open(URL))

with open(FILENAME, 'a') as f:
    writer = csv.writer(f, delimiter=';')
    for link in soup.find_all('a', class_=re.compile("hdrlnk")):
        timeset = time.strftime("%m-%d %H:%M")

        item_url = urljoin(BASE_URL, link['href'])
        item_soup = BeautifulSoup(opener.open(item_url))

        # do smth with the item_soup? or why did you need to follow this link?

        writer.writerow([timeset, link.text, item_url])

seems to work fine it could be that the tags are only extracted once for the initial document:
# Retrieve all of the anchor tags
tags = soup('a')
