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 running the function on some basic, single character inputs.

COMMAND: PYTHON(./temp/function.py a b c 1 2 3)
user:
Response: Function input - output pairs: (a, aJJI) (b, bJJI) (c, cJJI) (1, 1JJI) (2, 2JJI) (3, 3JJI) 

assistant:
Interesting, it seems that each input has "JJI" appended to it. Let's test it with some longer strings and special characters.

COMMAND: PYTHON(./temp/function.py hello world test !$%+)
user:
Response: Function input - output pairs: (hello, helloJJI) (world, worldJJI) (test, testJJI) (!$%+, !$%+JJI) 

assistant:
Based on the inputs and outputs tested, it seems that the function is appending "JJI" to the end of each input string.

[DESCRIPTION]: The function appends "JJI" to the given input string.

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