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, I'll start by testing the function with some input strings.

COMMAND: PYTHON(./temp/function.py "hello" "world" "test" "function" "12345")
user:
Response: Function input - output pairs: (hello, zero) (world, one) (test, zero) (function, zero) (12345, zero) 

assistant:
Thank you for the response. I'll test some more inputs to understand the function better.

COMMAND: PYTHON(./temp/function.py "apple" "banana" "cat" "dog" "elephant" "fish")
user:
Response: Function input - output pairs: (apple, zero) (banana, zero) (cat, zero) (dog, zero) (elephant, zero) (fish, zero) 

assistant:
Interesting, let me test a few more inputs.

COMMAND: PYTHON(./temp/function.py "this" "is" "a" "test" "example" "code")
user:
Response: Function input - output pairs: (this, zero) (is, zero) (a, zero) (test, zero) (example, zero) (code, zero) 

assistant:
It seems that only "world" returns "one" as output and everything else returns "zero". Let me test a few more words.

COMMAND: PYTHON(./temp/function.py "hello world" "worldwide" "new world" "global" "planet" "earth")
user:
Response: Function input - output pairs: (hello world, one) (worldwide, two) (new world, two) (global, zero) (planet, zero) (earth, zero) 

assistant:
[DESCRIPTION]: The function appears to return the number of times the substring "world" appears in the input string.

[CODE]:
```python
def approximate_function(input_string):
    return input_string.count('world')
```
