I am trying to do an assignment: write a Python program that expands on http://www.py4e.com/code3/urllinks.py. The program will use urllib to read the HTML from the data files below, extract the href= vaues from the anchor tags, scan for a tag that is in a particular position relative to the first name in the list, follow that link and repeat the process a number of times and report the last name you find. Actual problem: Start at: http://py4e-data.dr-chuck.net/known_by_Kylen.html Find the link at position 18 (the first name is 1). Follow that link. Repeat this process 7 times. The answer is the last name that you retrieve. Hint: The first character of the name of the last page that you will load is: P[enter image description here][1]
#Code I used:
import re
import urllib
import urllib.request
import urllib.parse
import urllib.error
from urllib.request import urlopen
from bs4 import BeautifulSoup
import ssl
ctx = ssl.create_default_context()
ctx.check_hostname = False
ctx.verify_mode = ssl.CERT_NONE
url = input('Enter URL:')
count = int(input('Enter count:'))
position = int(input('Enter position:'))-1
html = urllib.urlopen(url, context=ctx).read()
soup = BeautifulSoup(html,"html.parser")
href = soup('a')
#print href
for i in range(count):
link = href[position].get('href', None)
print(href[position].contents[0])
html = urllib.urlopen(link).read()
soup = BeautifulSoup(html,"html.parser")
href = soup('a')
But got an error: html = urllib.urlopen(url, context=ctx).read() AttributeError: module 'urllib' has no attribute 'urlopen'
Can anyone provide solutions for this?

You imported urlopen
already, but never used it. Instead you used urllib.urlopen
which doesn't exist.
Instead of using urllib.urlopen
just use urlopen
Example:
from urllib.request import urlopen
# before: html = urllib.urlopen(url, context=ctx).read()
html = urlopen(url, context=ctx).read()
