I am trying to pull only the links and their text from a webpage line by line and insert text and link into a dictionary. Without using beautiful soup or a regex.

i keep getting this error:

error:

Traceback (most recent call last):
File "F:/Homework7-2.py", line 13, in <module>
link2 = link1.split("href=")[1]
IndexError: list index out of range

code:

Python

import urllib.request
url = "http://www.facebook.com" 
page = urllib.request.urlopen(url)
mylinks = {}
links = page.readline().decode('utf-8')


for items in links:
  links = page.readline().decode('utf-8')
  if "a href=" in links:
     links = page.readline().decode('utf-8')
     link1 = links.split(">")[0]
     link2 = link1.split("href=")[1]
     mylinks = link2
     print(mylinks)

Solution 1

IndexError: list index out of range

The message is telling you that the index value is greater than the number of items in the list. You should not make assumptions about the results of commands, but check first. If the returned list has only one item then you need to code for that.
