# Write a function to open and read a file named StarWars.txt
# from http://www.cs.virginia.edu/~up3f/cs1110/practice-of-the-day/StarWars.txt
#
# Let's practice opening a file locally and via a URL (internet).
# That is,
# - for the first solution, you will download the file and
#   save it to your machine (same folder where your .py file is)
# - for the second solution, you will open the file via a URL
#
# The function will return 2 things (in order)
#   1. The number of StarWars' fans
#   2. The total number of respondents
#
# There are many fields for each line. You only need the following fields to complete this exercise:
#    RespondentID  (0)
#    Have you seen any of the 6 films in the Star Wars franchise?  (1)
#        -- possible value "Yes" or "No"
#    Do you consider yourself to be a fan of the Star Wars film franchise?  (2)
#        -- possible value "Yes" or "No"
#
#  Note: There are exactly 2 header lines.
#


## this solution reads a file locally
