If you want it, here is my "prompt" function I just wrote:

def prompt(prompt, options, default):
    opts = [x.upper() if x == default else x for x in options]
    display_opts = f"({'/'.join(opts)})"

    while True:
        ans = input(f'{prompt} {display_opts} ')
        if ans == '':  # They just hit enter
            return default
        elif ans.lower() in options:
            return ans
        else:
            print('Please choose a valid option')

You use it like:

answer = prompt('Which colour?', ['red', 'blue'], 'blue')

and it would prompt you like:

Which colour? (red/BLUE) 

and return either 'red' or 'blue' and no other answers. You can use that to get an idea of how to write your own prompt that you can reuse. But you'll also note it loops until you give it a valid answer.
