Answer 1

welcome to SO. Please note the change below, you use the variable friend without the i , since you can check with friend values and keys

def greetagain():

    friend = input("Enter your friend name or color? ")

    if friend in Friends.keys():
        print('yes it matches')
    elif friend in Friends.values():
        print('ok ok')
    else:
        print('subscribe')

i could only understand a part of your question, so, i have tried my best to explain it.

The if condition already works as it is. I think you want to retrieve the name of the friend (key) in the elif condition, for that you can try the following code:

Friends = { 'rolf' : 'blue', 'ronnie' : 'green', 'barbara' : 'purple', 'benny' : 'kaki', 'stewart' : 'yellow', 'mickey' : 'red' }

def greetagain():
    friend = input("Enter your friend name or color? ")

    if friend in Friends.keys():
        print('Key matches')
        print("Color associted to friend is:", Friends[friend])
    elif friend in Friends.values():
        for key, value in Friends.items(): 
            if friend == value: 
                print('Color is present in list and associated by:', key)
    else:
        print('subscribe')

greetagain()
