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 on some sample input strings. 

COMMAND: PYTHON(./temp/function.py "hello" "world" "test" "123" "function" "python")
user:
Response: Function input - output pairs: (hello, lyccr) (world, grqcd) (test, zynz) (123, 123) (function, tokszjrk) (python, vpzlrk) 

assistant:
Let's test the function with single characters to see if we can identify a pattern.

COMMAND: PYTHON(./temp/function.py "a" "b" "c" "d" "e" "f" "g" "h" "i" "j" "k" "l" "m" "n" "o" "p" "q" "r" "s" "t" "u" "v" "w" "x" "y" "z")
user:
Response: Function input - output pairs: (a, w) (b, a) (c, s) (d, d) (e, y) (f, t) (g, i) (h, l) (i, j) (j, x) (k, m) (l, c) (m, f) (n, k) (o, r) (p, v) (q, e) (r, q) (s, n) (t, z) (u, o) (v, u) (w, g) (x, h) (y, p) (z, b) 

assistant:
It seems the function is applying a transformation to each character in the input string. Let's test with some special characters and digits to further analyze the pattern.

COMMAND: PYTHON(./temp/function.py "!" "@" "#" "$" "%" "^" "&" "*" "(" ")" "0" "1" "2" "3" "4" "5" "6" "7" "8" "9")
user:
Response: Function input - output pairs: (!, !) (@, @) (#, #) ($, $) (%, %) (^, ^) (&, &) (*, *) ((, () (), )) (0, 0) (1, 1) (2, 2) (3, 3) (4, 4) (5, 5) (6, 6) (7, 7) (8, 8) (9, 9) 

assistant:
Based on the outputs, it appears that the function applies a specific character transformation only on alphabetic characters and leaves special characters/digits unchanged. The transformation seems to be consistent for the same input character. Let's try to derive the character transformation logic.

[DESCRIPTION]: The function takes an input string and applies a specific character transformation only on alphabetic characters, leaving special characters and digits unchanged. 

[CODE]:
```python
def approx_function(input_str):
    transformation = {
        'a': 'w', 'b': 'a', 'c': 's', 'd': 'd', 'e': 'y', 'f': 't', 'g': 'i', 'h': 'l', 'i': 'j',
        'j': 'x', 'k': 'm', 'l': 'c', 'm': 'f', 'n': 'k', 'o': 'r', 'p': 'v', 'q': 'e', 'r': 'q',
        's': 'n', 't': 'z', 'u': 'o', 'v': 'u', 'w': 'g', 'x': 'h', 'y': 'p', 'z': 'b'
    }
    output_str = ''.join([transformation.get(char, char) for char in input_str])
    return output_str
```

Let's test this approximation with a few more inputs.

COMMAND: PYTHON(./temp/function.py "alphabet" "uvwxyz" "Example" "analysis")
