Exercise: Check Monster Character Exists Description In this series of exercises, you will create functions to create, modify and examine dictionaries that represent characters in an animated film, and the cast members who voice the characters. The keys of the dictionary will be character names. The values in the dictionary will be voice actor names. For this exercise, you will create a function that checks if a character is already in the dictionary. Files - monsterfunctions . py : set of functions to work with monster cast dictionaries. Action Checks if character is a key in monsters. Return Value True if character is a key in monsters, otherwise False. Examples monsters = create_monster_cast ( ) monsters = add_cast_member(monsters, "Mike", "William Crystal") has_character(monsters, "Mike") > True has_character(monsters, "Sully") > False
