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.

Let's start by providing some input strings to the function and analyze the output.

COMMAND: PYTHON(./temp/function.py "apple" "hello" "world" "test" "12345")
user:
Response: Function input - output pairs: (apple, appletljeL) (hello, hellotljeL) (world, worldtljeL) (test, testtljeL) (12345, 12345tljeL) 

assistant:
That was interesting. Let's try some more inputs to have a better understanding.

COMMAND: PYTHON(./temp/function.py "banana" "abcdefghijklmnopqrstuvwxyz" "1234567890" "CAPITALS" "sPaCeS")
user:
Response: Function input - output pairs: (banana, bananatljeL) (abcdefghijklmnopqrstuvwxyz, abcdefghijklmnopqrstuvwxyztljeL) (1234567890, 1234567890tljeL) (CAPITALS, CAPITALStljeL) (sPaCeS, sPaCeStljeL) 

assistant:
From the given output, it appears that the function is appending the string "tljeL" to each input string. Here is the description and the code.

[DESCRIPTION]: The function appends the string "tljeL" to the end of the input string.
[CODE]: 
```python
def function_approximation(input_string):
    return input_string + "tljeL"
```
