My first program is a bit faulty. Please Help.

I suggest to think more thoroughly about logic of your program.

For example: how should code handle situation when user enters neither 'yes' or 'no'?

My suggestion is to refactor code:

- input validation function - keeps asking for input until either yes or no is entered by user; as this is needed only for deciding what to do next, it should return True or False
- two branch conditional - play game; quit

if validated_answer('Lets play this game,shall we? (Answer yes or no) '):
    # play game
else:
    # quit game

Regarding validation function:

- keep asking question (while True):
- make answer lowercase so that comparison is easier
- if answer is 'yes' return True; if 'no' return False (exits function)
- else print message to user (while loop continues)

Something along those lines:

def validated_answer(request): 
    while True: 
        answer = input(request).lower() 
        if answer == 'yes': 
            return True 
        elif answer == 'no': 
            return False 
        else: 
            print('Answer must be yes or no! ')
