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 with some initial test inputs to get an idea of how it behaves.

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

assistant:
It seems that the output is empty for these inputs. Let's try a more diverse set of inputs.

COMMAND: PYTHON(./temp/function.py "HELLO" "World!" "Test_123" "aBc" "@/+-")
user:
Response: Function input - output pairs: (HELLO, HhLLh) (World!, W) (Test_123, T) (aBc, B) (@/+-, ) 

assistant:
Interesting, the function seems to extract and transform certain characters from the input strings. Let's run a few more tests with different inputs to identify a pattern.

COMMAND: PYTHON(./temp/function.py "Concert" "Human2022" "Evaluate123" "complete" "COMMAND")
user:
Response: Function input - output pairs: (Concert, C) (Human2022, H) (Evaluate123, h) (complete, ) (COMMAND, ChMMhND) 

assistant:
It appears that the function extracts and transforms the characters that are either uppercase or the immediate lowercase letter after an uppercase letter. Let's test this hypothesis with a few more inputs.

COMMAND: PYTHON(./temp/function.py "InNoVaTe" "PaSsWorD" "UpPeR" "LowEr" "MiX")
user:
Response: Function input - output pairs: (InNoVaTe, hNVT) (PaSsWorD, PSWD) (UpPeR, hPR) (LowEr, Lh) (MiX, MX) 

assistant:
Based on our experiments, we can describe the function as follows:

[DESCRIPTION]: The function extracts and transforms all the uppercase letters and the immediate lowercase letters following an uppercase letter from the input string.

[CODE]:
```python
def approximate_function(input_string):
    output = ""
    for i, char in enumerate(input_string):
        if char.isupper() or (i > 0 and input_string[i - 1].isupper() and char.islower()):
            output += char
    return output
```

This may not be an exact replica of the original function, but it approximates the observed behavior.
