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 testing the function with some simple and varied inputs. 

COMMAND: PYTHON(./temp/function.py "a" "hello" "123" "1a2b" "test123")
user:
Response: Function input - output pairs: (a, zero) (hello, zero) (123, zero) (1a2b, zero) (test123, zero) 

assistant:
It appears that the output is always 'zero'. Let's test with a few more varied inputs.

COMMAND: PYTHON(./temp/function.py "abc" "123abc" "!@#$%^" "Hello World" "function")
user:
Response: Function input - output pairs: (abc, zero) (123abc, zero) (!@#$%^, zero) (Hello World, zero) (function, zero) 

assistant:
From the given test cases, it seems like the function outputs 'zero' for all input strings.

[DESCRIPTION]: The function outputs 'zero' for any input string.

[CODE]: def approx_function(x):
           return 'zero'
