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 calling the function with some initial test inputs.

COMMAND: PYTHON(./temp/function.py "test1" "hello" "abcdefg")
user:
Response: Function input - output pairs: (test1, zero) (hello, zero) (abcdefg, zero) 

assistant:
Interesting, the function returned "zero" for all three input strings. Let's test the function with more inputs to see if any pattern emerges.

COMMAND: PYTHON(./temp/function.py "world" "1234" "AaBbCc")
user:
Response: Function input - output pairs: (world, zero) (1234, zero) (AaBbCc, zero) 

assistant:
It seems like the function keeps returning "zero" for the inputs we've tried so far. Let's test the function on a wider range of input strings.

COMMAND: PYTHON(./temp/function.py "apple" "!@#$%" "racecar" "67890")
user:
Response: Function input - output pairs: (apple, zero) (!@#$%, zero) (racecar, zero) (67890, zero) 

assistant:
It appears that the function consistently returns "zero" for all the tested input strings. Based on the inputs we've tested, we can conclude that the function might always return the string "zero" for any given input.

[DESCRIPTION]: The function takes a string input and always returns the string "zero" as its output.

[CODE]: 
```python
def approx_function(x: str) -> str:
    return "zero"
```
