Hi, your job is to interpret a function f(x) that is implemented in the ./temp/function.py script. f(x) takes string inputs.
All you can do is call f(x) on an input string by running PYTHON(./temp/function.py string). 
Try to describe the function implemented by f(x) by running experiments on it. 
You can call the function on multiple inputs at a time by running PYTHON(./temp/function.py string1 string2 string3 ...). 
We encourage testing a large range of inputs before writing a description.
The goal is to find a good simple description of f(x) that explains most of the function behavior. f(x) may combine multiple different operations.
Your description of the function should be in the following form.
[DESCRIPTION]: Describe what the function is doing in language. 
[CODE]: Write python code that approximates the behavior of the function.

Alright, let's start by running the function on a few examples to get a better understanding of its behavior. 

COMMAND: PYTHON(./temp/function.py "hello" "world" "test" "123" "a" "ab" "ba" "abc")
user:
Response: Function input - output pairs: (hello, ) (world, ) (test, ) (123, ) (a, ) (ab, ) (ba, ) (abc, ) 

assistant:
It seems like the function is not providing any output for these inputs. Let's try some other inputs.

COMMAND: PYTHON(./temp/function.py "uppercase" "lowercase" "digits" "special_chars" "space")
user:
Response: Function input - output pairs: (uppercase, ) (lowercase, ) (digits, ) (special_chars, ) (space, ) 

assistant:
I see, the function is not providing any output for these inputs either. Let's try some inputs that include digits, special characters, or whitespace.

COMMAND: PYTHON(./temp/function.py "1hello" "world!" "test 123" "a_b" "!@#")
user:
Response: Function input - output pairs: (1hello, ) (world!, ) (test 123, ) (a_b, ) (!@#, ) 

assistant:
It appears that the function might be returning empty outputs for all inputs. Let's try some more inputs.

COMMAND: PYTHON(./temp/function.py "Python" "Java" "C++" "Ruby" "HTML")
user:
Response: Function input - output pairs: (Python, P) (Java, J) (C++, C) (Ruby, R) (HTML, HTML) 

assistant:
Based on these responses, it appears that the function might be returning the first capital letter in the input string. Let's test with some more inputs.

COMMAND: PYTHON(./temp/function.py "Programming" "Languages" "MachineLearning" "CamelCase" "NoCaps")
user:
Response: Function input - output pairs: (Programming, P) (Languages, L) (MachineLearning, ML) (CamelCase, CC) (NoCaps, NC) 

assistant:
Based on the responses so far, it seems that the function is extracting the capital letters from the given input string. Here is the description and the code that approximates the behavior of the function:

[DESCRIPTION]: The function f(x) extracts the capital letters from the given input string x.

[CODE]:
```
def extract_capital_letters(s: str) -> str:
    return ''.join([char for char in s if char.isupper()])
```
