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. 
assistant:
Alright, let's start by testing the function with some different input strings. 

COMMAND: PYTHON(./temp/function.py "hello" "world" "12345" "test input")
user:
Response: Function input - output pairs: (hello, helloln) (world, worldln) (12345, 12345ln) (test input, test inputln) 

assistant:
It seems that the function is appending 'ln' to the input strings. Let's perform some more tests to confirm this behavior.

COMMAND: PYTHON(./temp/function.py "python" "example" "abcdefg" "happy")
user:
Response: Function input - output pairs: (python, pythonln) (example, exampleln) (abcdefg, abcdefgln) (happy, happyln) 

assistant:
Based on the experiment results, we can make the following approximation for the function f(x):

[DESCRIPTION]: The function appends 'ln' to the input string.

[CODE]:
```python
def f(x):
    return x + "ln"
```

Let's test a few more inputs to be sure.

COMMAND: PYTHON(./temp/function.py "This is" "a sentence" "!@#$%^&*()" "more tests")
