''' Purpose: introducing the acquisition of web data -- determine the hidden
        super power of a CS 1112 person
'''

# need help to get web data - so import some capabilities
import urllib.request

# define the base folder for course participants
BASE_PEOPLE_URL = 'http://www.cs.virginia.edu/~cs1112/people/'

# get computing id of interest and clean it up into canonical form;
# i.e., in lowercase and without surrounding whitespace

reply = input( 'Enter computing id: ' )

id = reply.strip() 
id = id.lower() 

# specify web folder of indicated person
folder = BASE_PEOPLE_URL + id + '/'  

# specify link for super power web file of indicated person
web_file = folder + 'power.txt'

# get a connection to the web resource of interest
stream = urllib.request.urlopen( web_file )

# read stream to get its contents (the returned contents are not
# normal text)
bytes = stream.read()  

# decode contents into plain text form
contents = bytes.decode( 'UTF-8' )

# text is the superpower of interest
print( contents )
