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. Do not test any additional inputs.
After testing these 10 inputs, 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: ["Rhine", "Tokyo", "apple", "Zircon", "The Grapes of Wrath", "The Barber of Seville", "phone", "Bear", "Wolf", "Ankara"] 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 "Rhine" "Tokyo" "apple" "Zircon" "The Grapes of Wrath" "The Barber of Seville" "phone" "Bear" "Wolf" "Ankara")

Response: Function input - output pairs: (Rhine, 863 km) (Tokyo, undefined) (apple, undefined) (Zircon, undefined) (The Grapes of Wrath, undefined) (The Barber of Seville, undefined) (phone, undefined) (Bear, undefined) (Wolf, undefined) (Ankara, undefined)

[DESCRIPTION]: The function, f(x), seems to apply a rule that returns the length of a geographical feature (in kilometers) if the input is a geographical feature, otherwise it returns "undefined".

[DOMAIN]: The domain of the function f(x) includes geographical features such as rivers, mountain ranges, etc. The function does not apply its rule to other types of input, like cities, objects, animals, or book titles, as those return "undefined".
