# Function that finds users with a certain interest

#----------------------------------------------------------

def data_scientists_who_like(target_interest):

  return [user_id

      for user_id, user_interest in interests

      if user_interest == target_interest]

 

#----------------------------------------------------------

#-- PROVIDE ANSWERS to the following questions (01) in python code:

#-- include code that prints the user id of those who are interested in R

#-- include code that prints the user id of those who are interested in Python

#-- hint: each of the above questions could be answered using one line of code

#--   the "interests" list contains the user id and the interest of that user

#--   combine the function (data_scientists_who_like) with a print statement to answer each of the questions

#----------------------------------------------------------

 

#----------------------------------------------------------

#-- PROVIDE ANSWERS to the following questions (02) in python code:

#-- include code that prints the name of those users who are interested in R

#-- include code that prints the name of those users who are interested in Python

#-- hint: if you answer question 01, this should be fairly straight forward

#--   the code will need to iterate through the list the function (data_scientists_who_like) returns, and then print the name from the users list
