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 testing the function with various inputs. 

COMMAND: PYTHON(./temp/function.py "hello" "world" "test" "123" "abc")
user:
Response: Function input - output pairs: (hello, zero) (world, zero) (test, zero) (123, zero) (abc, zero) 

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

COMMAND: PYTHON(./temp/function.py "HELLO" "WORLD" "TEST" "1.23" "#$%@")
user:
Response: Function input - output pairs: (HELLO, zero) (WORLD, zero) (TEST, zero) (1.23, zero) (#$%@, zero) 

assistant:
Seems like the function might only be returning "zero" so far. Let's try some more inputs to confirm.

COMMAND: PYTHON(./temp/function.py "example" "foo" "bar" "1234" "test123")
user:
Response: Function input - output pairs: (example, zero) (foo, zero) (bar, zero) (1234, zero) (test123, zero) 

assistant:
Based on the outputs, it appears that the function is simply returning "zero" for all input strings it receives.

[DESCRIPTION]: The function returns the string "zero" for any input string provided.

[CODE]: 
```python
def approx_function(input_string):
    return "zero"
```
