Question
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
