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 some tests on the f(x) function. I will run a few simple inputs to see its output.

COMMAND: PYTHON(./temp/function.py "a" "b" "c" "A" "B" "C" "1" "2" "3")
user:
Response: Function input - output pairs: (a, alF) (b, blF) (c, clF) (A, AlF) (B, BlF) (C, ClF) (1, 1lF) (2, 2lF) (3, 3lF) 

assistant:
Interesting, let's try some more inputs including special characters and spaces.

COMMAND: PYTHON(./temp/function.py " " "!" "?" "%" "abc" "123" "AaBbCc")
user:
Response: Function input - output pairs: ( ,  lF) (!, !lF) (?, ?lF) (%, %lF) (abc, abclF) (123, 123lF) (AaBbCc, AaBbCclF) 

assistant:
Based on the given responses, it seems that the function is appending "lF" to every input string. I will write a simple description of the function and provide a corresponding Python code.

[DESCRIPTION]: The function appends "lF" to the given input string.
[CODE]:
```python
def approximate_function(x):
    return x + "lF"
```
