Further to earlier explanation (and slightly wary because I don't use 
Idle), instead of declaring a main function, consider another common 
Python idiom:

if __name__ == "__main__":
     dictionary = createDictionary()
     print(dictionary['two'])
     print(dictionary['red'])

(should) continue to work, plus leave access to dictionary thereafter.
