''' Purpose: determine the hidden super power of a CS 1112 person
'''

# need help to get web data - so import the capability
from urllib.request import urlopen

# define the base folder for course participants
BASE_CS1112_PEOPLE_URL = 'http://www.cs.virginia.edu/~cs1112/people/'
# So the people folder is the base folder! The people
# folder contains all of your submissions! :)
FILE_NAME = 'my-power.txt'

# get computing id of interest
reply = input( 'Enter computing id: ' )
# If I write "   nAh3zb"
# clean up the reply to get the user id
user_id = reply.strip() # Remove leading and trailing whitespace ("nAh3zb")
user_id = user_id.lower() # Make the user_id lowercase now ("nah3zb")

# specify web folder of indicated person
web_folder = BASE_CS1112_PEOPLE_URL + user_id + '/'
# people/compid/ <- this is the last slash!
print( "Web folder = ", web_folder )
# specify link for super power web file of indicated person
link = web_folder + FILE_NAME
print( "Link=", link )
# get a connection to stream the web resource of interest
stream = urlopen( link )
# It's just a connection to the web where it goes into that link and
# establishes a connection with that link.
# read stream to gets its encoded contents
encoding = stream.read()
# Now take that connection and read what's in the stream (that connection)
# decode contents into plain text form
text = encoding.decode( 'UTF-8' )
# Take the encoded version and decode it using plain old text.
print( text )
# cleaned-up text is the superpower of interest
power = text.strip()

# print power
print( power )

# So we see how we went to the folder people and then took a computing
# id, went into that person's directory, and then got their my-power.txt
# and then got the contents of that webpage, decoded it, and then
# printed out their power!
