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 a few basic tests on the function.

COMMAND: PYTHON(./temp/function.py a b c)
user:
Response: Function input - output pairs: (a, asefuZ) (b, bsefuZ) (c, csefuZ) 

assistant:
Interesting, let's try with some longer inputs and numeric inputs.

COMMAND: PYTHON(./temp/function.py abcd 123 123abc)
user:
Response: Function input - output pairs: (abcd, abcdsefuZ) (123, 123sefuZ) (123abc, 123abcsefuZ) 

assistant:
It seems that the function simply appends a set string to the input. Let's run some tests with special characters and whitespace to confirm this behavior.

COMMAND: PYTHON(./temp/function.py "hello world" "!@#$%^&*()")
user:
Response: Function input - output pairs: (hello world, hello worldsefuZ) (!@#$%^&*(), !@#$%^&*()sefuZ) 

assistant:
Based on the output, it looks like the function is appending the string "sefuZ" to the end of the input string. Here is the description and the code:

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

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