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 testing some simple inputs. 

COMMAND: PYTHON(./temp/function.py "a" "b" "c")
user:
Response: Function input - output pairs: (a, a) (b, b) (c, c) 

assistant:
Let's try some more inputs including digits and special characters.

COMMAND: PYTHON(./temp/function.py "1" "2" "3" "@" "#" "$")
user:
Response: Function input - output pairs: (1, 1) (2, 2) (3, 3) (@, @) (#, #) ($, $) 

assistant:
Now let's test it with some longer strings, including words, digits, and special characters.

COMMAND: PYTHON(./temp/function.py "hello" "world" "12345" "!@#$%")
user:
Response: Function input - output pairs: (hello, hvllo) (world, world) (12345, 12345) (!@#$%, !@#$%) 

assistant:
Interesting, let's test with more words and a mix of characters.

COMMAND: PYTHON(./temp/function.py "python" "function" "test" "a1b2" "&*$#!")
user:
Response: Function input - output pairs: (python, python) (function, function) (test, tvst) (a1b2, a1b2) (&*0!, &*0!) 

assistant:
Based on the input-output pairs, it seems that the function replaces specific characters in the input string with specific alternative characters. Let's try some inputs focusing on vowels, since 'e' was replaced by 'v'.

COMMAND: PYTHON(./temp/function.py "aeiou" "EAIOU" "aeiouAEIOU")
user:
Response: Function input - output pairs: (aeiou, aviou) (EAIOU, EAIOU) (aeiouAEIOU, aviouAEIOU) 

assistant:
[DESCRIPTION]: The function replaces the lowercase vowel 'e' with 'v' in the input string. It keeps all other characters the same.

[CODE]:
```python
def approximate_function(input_string):
    return input_string.replace('e', 'v')
```
