# This program keeps track of a group of friends for you.

#Here are the functions to be filled in:


#  Task 1. Prompt user for friend's info and add it to the dictionary
#  I have done most of it: Your job is to think of one more kind of information to prompt the
#  user for and add that info to the afriend dictionary.  

def addAFriend (friends):
    name  = input("What is the name?:  ")
    month = int (input( "What month is the birthday? "))
    day   = int (input("What day is the birthday? "))
    score = int (input("How close is this friend[0=acquaintance, 5=bff] ?: " ))

    #your code goes here.  Note birthday is a tuple.

    

    afriend = {"name":name, "birthday":(day, month), "friendship-score": score}

    friends.append( afriend )  #append it to the friend list
    return friends

# Task 2. Replace the print statment with code to print all the names (names only) in the list of friends. 
def printFriends(friends):
    print ("Not implemented")
    return None 


# Task 3. Replace the print statement with code to prompt the user for a friendship score [0=acquaintance, 5=bff]
# go through the friends list, and and print only the names of friends with higher scores

def printCloseFriends(friends):  
     print ("Not implemented")
     return None 
    

# Task 4. Ask user for a friend's name, find the friend in the list, and print all the info associated with that friend,
# including keys and values.  If the friend is not in the list, apologize and let the user try again.

def findFriend (friends) :
    print("Not implemented")
    return None 


# Task 5. Go through the list of friends. Print the name of each friend and invite the user to change the friendship score.
# Also invite the user to give a reason (a string) for changing the score.  Add a new item --  "memo":reason  -- to the entry.
# (some friends will have this memo key/value and some won't).  

def changeFriendshipStatus (friends):
    print ("Not implemented.")
    return friends 



#----- Get a command from user and return it:
def getCommandFromUser( options ):

    while True:

        for opt in options:
