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 by running the function with a few different string inputs. 

COMMAND: PYTHON(./temp/function.py "hello" "world" "python" "123" "test")
user:
Response: Function input - output pairs: (hello, ) (world, ) (python, ) (123, ONE TWO THREE) (test, ) 

assistant:
Interesting, it seems like the function is not outputting anything for the first four inputs but is converting numbers in the last input to their spelled-out form. Let's test the function with more number inputs and some combined inputs.

COMMAND: PYTHON(./temp/function.py "42" "567" "981" "hello123" "5five" "apples12")
user:
Response: Function input - output pairs: (42, FOUR TWO) (567, FIVE SIX SEVEN) (981, NINE EIGHT ONE) (hello123, ONE TWO THREE) (5five, FIVE) (apples12, ONE TWO) 

assistant:
[DESCRIPTION]: The function takes a string input and returns the string with any numbers it contains converted to their spelled-out form, while it removes all characters which are not digits.

[CODE]: 
```python
def approximate_function(input_string):
    number_mapping = {
        '0': 'ZERO', '1': 'ONE', '2': 'TWO', '3': 'THREE', '4': 'FOUR',
        '5': 'FIVE', '6': 'SIX', '7': 'SEVEN', '8': 'EIGHT', '9': 'NINE'
    }
    
    output_string = ''.join([number_mapping[char] if char.isdigit() else '' for char in input_string])
    return output_string
```

Let's run the approximate function a few more times to see if it consistently matches the behavior of the original function.

COMMAND: PYTHON(./temp/function.py "combination123" "5random_characters" "testing982" "00112233445566778899")
