Build an RPG Character

Please Help the 10th task is not working.

full_dot = '●'
empty_dot = '○'

def create_character(name, strength, intelligence, charisma):
    if not isinstance(name, str): 
        return "The character name should be a string"
    if len(name) >= 10:

    character_string = name
    for key in ['STR', 'INT', 'CHA']:
        stat = stats[key]
        character_string += f'\n{key} {full_dot * stat}{empty_dot * (10 - stat)}'

    print(character_string)
    return character_string
