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.

I will start by running a few initial tests to understand the behavior of the f(x) function. Please provide the output for the following inputs:

COMMAND: PYTHON(./temp/function.py a b c 1 2 3)
user:
Response: Function input - output pairs: (a, aNZ) (b, bNZ) (c, cNZ) (1, 1NZ) (2, 2NZ) (3, 3NZ) 

assistant:
I will test some more inputs to better understand the function.

COMMAND: PYTHON(./temp/function.py hello world 123 test)
user:
Response: Function input - output pairs: (hello, helloNZ) (world, worldNZ) (123, 123NZ) (test, testNZ) 

assistant:
Based on the outputs provided, it seems like the function appends the string "NZ" to the input string.

[DESCRIPTION]: The function takes an input string and appends "NZ" to it.
[CODE]: 
```python
def f(x):
    return x + "NZ"
```

Let's test some more inputs just to be sure.

COMMAND: PYTHON(./temp/function.py dog cat apple)
