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 calling the f(x) function with a few different string inputs.

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

assistant:
Let's try more inputs to understand the behavior of the function better.

COMMAND: PYTHON(./temp/function.py "example" "python" "assistant" "qwerty")
user:
Response: Function input - output pairs: (example, example) (python, python) (assistant, aKKiKtant) (qwerty, qwerty) 

assistant:
It seems that the function is replacing some characters in the input strings. Let's try to find a pattern by testing with more inputs.

COMMAND: PYTHON(./temp/function.py "abcdef" "ghijkl" "mnopqr" "stuvwxyz")
user:
Response: Function input - output pairs: (abcdef, abcdef) (ghijkl, ghijkl) (mnopqr, mnopqr) (stuvwxyz, Ktuvwxyz) 

assistant:
The function appears to replace the character 's' with a capital 'K'. Let's test some more inputs to confirm this behavior.

COMMAND: PYTHON(./temp/function.py "success" "strings" "simple" "special")
user:
Response: Function input - output pairs: (success, KucceKK) (strings, KtringK) (simple, Kimple) (special, Kpecial) 

assistant:
Based on the input-output pairs, f(x) seems to replace all occurrences of the letter 's' with a capital 'K'.

[DESCRIPTION]: The function replaces every occurrence of the letter 's' in the input string with a capital 'K'.

[CODE]:
```python
def f(x):
    return x.replace('s', 'K')
```
