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 testing some simple inputs. 

COMMAND: PYTHON(./temp/function.py "a" "b" "c")
user:
Response: Function input - output pairs: (a, aYl) (b, bYl) (c, cYl) 

assistant:
Interesting, let's try some more inputs.

COMMAND: PYTHON(./temp/function.py "hello" "world" "python")
user:
Response: Function input - output pairs: (hello, helloYl) (world, worldYl) (python, pythonYl) 

assistant:
Let's test some numeric inputs and special characters.

COMMAND: PYTHON(./temp/function.py "123" "!@#" "test123")
user:
Response: Function input - output pairs: (123, 123Yl) (!@#, !@#Yl) (test123, test123Yl) 

assistant:
[DESCRIPTION]: It appears that the function takes the input string and appends "Yl" to it.

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