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.

Function Name

has_character

Parameters

monsters: a dictionary
character: a string, the name of a character

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
