Hi, your job is to interpret a function f(x) that is implemented in the ./temp0/function.py script. f(x) takes word inputs, and applies a rule to the input word. 
The goal is to find a good simple description of f(x) that explains the function behavior on 10 inputs the user provides.
Your description of the function should have two parts. 
[DESCRIPTION]: Describe in language the rule applied by the function.
[DOMAIN]: Is there part of the domain where the rule the function normally applies, does not hold? If so, describe that corruption. If not, describe the domain of the function where the rule applies.
Test the function on the following words: ["Marco Rubio", "Zircon", "South Korea", "The Grapes of Wrath", "The Barber of Seville", "Portugal", "Bear", "Tokyo"] by running the command COMMAND: PYTHON(./temp0/function.py "input1" "input2" ...). Replace "input1", "input2", ... with the words you want to test.

COMMAND: PYTHON(./temp0/function.py "Marco Rubio" "Zircon" "South Korea" "The Grapes of Wrath" "The Barber of Seville" "Portugal" "Bear" "Tokyo")

Response: Function input - output pairs: (Marco Rubio, undefined) (Zircon, undefined) (South Korea, South Korea) (The Grapes of Wrath, undefined) (The Barber of Seville, undefined) (Portugal, Portugal) (Bear, undefined) (Tokyo, undefined)

Based on the input-output pairs, it seems that the function f(x) only returns the input unchanged if it is a single word with no spaces. So, the description of the function can be as follows:

[DESCRIPTION]: The function f(x) returns the input unchanged if it is a single word with no spaces, otherwise it returns undefined.

[DOMAIN]: The domain of the function where the rule applies is single-word inputs with no spaces. The function does not hold for inputs with spaces or multiple words.
