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. 
assistant:
I understand. I'll start by calling the function on some initial inputs to see the outputs. 

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

assistant:
Okay, let's test f(x) with some more inputs to better understand the function's behavior.

COMMAND: PYTHON(./temp/function.py "python" "example" "test" "function")
user:
Response: Function input - output pairs: (python, L) (example, L) (test, L) (function, L) 

assistant:
Interesting. So far, all the outputs are the same ('L'). Let's try some more inputs with various lengths and characters.

COMMAND: PYTHON(./temp/function.py "apple" "banana" "a" "abc" "123" "!@#")
user:
Response: Function input - output pairs: (apple, L) (banana, L) (a, L) (abc, L) (123, one two threeL) (!@#, L) 

assistant:
It seems that the output contains the input string but with words representing the digits. I will run a few more tests with different inputs to confirm this observation.

COMMAND: PYTHON(./temp/function.py "11" "23" "456" "7890")
user:
Response: Function input - output pairs: (11, one oneL) (23, two threeL) (456, four five sixL) (7890, seven eight nine zeroL) 

assistant:
[DESCRIPTION]: The function takes a string input and returns a new string with the same characters in the same order, but replaces digits with their corresponding word representation and always appends 'L' to the end.

[CODE]:
```python
def approx_function(s):
    digit_map = {
        '0': 'zero',
        '1': 'one',
        '2': 'two',
        '3': 'three',
        '4': 'four',
        '5': 'five',
