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. We provide two files for this assignment.

I have to write a program that will read the HTML from this link ( http://python-data.dr-chuck.net/known_by_Maira.html ), extract the href= values 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.

Find the link at position 3 (the first name is 1). Follow that link. Repeat this process 4 times. The answer is the last name that you retrieve. 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.

Instead, I defined a function that prints the relevant link for any given url. Initially, the function will use the Fikret.html url as input. Subsequent inputs rely on refreshed urls that appear on the required position.
