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 testing some simple inputs. 

COMMAND: PYTHON(./temp/function.py "A" "B" "C")
user:
Response: Function input - output pairs: (A, ArFtrZ) (B, BrFtrZ) (C, CrFtrZ) 

assistant:
Interesting. Let's test some more inputs, including longer strings.

COMMAND: PYTHON(./temp/function.py "AA" "AB" "Hello" "World")
user:
Response: Function input - output pairs: (AA, AArFtrZ) (AB, ABrFtrZ) (Hello, HellorFtrZ) (World, WorldrFtrZ) 

assistant:
Let's check how the function handles empty strings and special characters.

COMMAND: PYTHON(./temp/function.py "" "!" "?" "#")
user:
Response: Function input - output pairs: (, rFtrZ) (!, !rFtrZ) (?, ?rFtrZ) (#, #rFtrZ) 

assistant:
Based on the provided input-output pairs, it seems that the function adds the string "rFtrZ" to the end of the given input. Here's my description and approximation of the function:

[DESCRIPTION]: The function appends the string "rFtrZ" to the end of the input string.

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

If you have more inputs to test, feel free to provide them, and I'll help evaluate the function further.
