Following Links in HTML Using BeautifulSoup.py

'''
Following Links in Python

In this assignment you will write a Python program that expands on http://www.pythonlearn.com/code/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.

We provide two files for this assignment. One is a sample file where we give you the name for your testing and the other is the actual data you need to process for the assignment

Sample problem: Start at http://python-data.dr-chuck.net/known_by_Fikret.html
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.
Sequence of names: Fikret Montgomery Mhairade Butchi Anayah
Last name in sequence: Anayah
Actual problem: Start at: http://python-data.dr-chuck.net/known_by_Blanka.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: L
