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: ["Bulgaria", "Greece", "Adam", "Tokyo", "Marco Rubio", "Fidelio", "Ankara", "Mexico"] by running the command COMMAND: PYTHON(./temp0/function.py "input1" "input2" ...). Replace "input1", "input2", ... with the words you want to test.
assistant:
COMMAND: PYTHON(./temp0/function.py "Bulgaria" "Greece" "Adam" "Tokyo" "Marco Rubio" "Fidelio" "Ankara" "Mexico")
user:
Response: Function input - output pairs: (Bulgaria, Sofia) (Greece, Athens) (Adam, undefined) (Tokyo, undefined) (Marco Rubio, undefined) (Fidelio, undefined) (Ankara, Ankara) (Mexico, Mexico) 

assistant:
Thank you for providing the input and output pairs. Based on the given data, I can provide the following description of the function:

[DESCRIPTION]: The function f(x) seems to return the capital city of a given input country. If the input is not a country or the function is unable to determine the capital, it returns "undefined".

[DOMAIN]: The domain of the function is limited to country names where the rule holds and returns their respective capital cities. For names that are not countries or cannot be recognized by the function, the rule does not hold, and the output is "undefined".
