# 1. create a file called "friends.csv"
# 2. gather the following information 5 friends:
#       name
#       email address
#       favorite cartoon (or movie)
#    for each friend, record the information in one line in friends.csv,
#    separate each piece of information with a comma (,)
# 3. write a function to read the file
#       using open() and read()
# 4. write a function to read the file
#       using open() and readlines()
# 5. write a function to read the file
#       using open() and readline()
# 6. write a function to read the file
#       using with open()
# 7. write a function to read the file and
#    process the information
#       split the information into pieces (reminder, we have csv, thus split by a comma)
#       store the information in a dictionary, where
#          key is (friend) name
#          value is list containing email and cartoon, that is, [email, cartoon]
#    the function then returns the newly created dictionary
#
# additional practice
# 8. modify the function from step 7 to allow multiple email address and
#    favorite cartoon
#    hint: instead of having a single list as value, you may
#          consider value as [ [list-of-emails], [list-of-cartoons] ]
#          or { 'email':[list-of-emails], 'cartoon':[list-of-cartoons] }
