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 some single-letter strings to observe the outputs.

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, g) (b, v) (c, a) (d, l) (e, c) (f, x) (g, u) (h, o) (i, b) (j, t) (k, p) (l, n) (m, w) (n, h) (o, f) (p, q) (q, k) (r, i) (s, m) (t, j) (u, s) (v, y) (w, r) (x, d) (y, z) (z, e) 

assistant:
Let's try running the function with strings containing more than one letter to see if it behaves differently with longer strings.

COMMAND: PYTHON(./temp/function.py hello world python function test)
user:
Response: Function input - output pairs: (hello, ocnnf) (world, rfinl) (python, qzjofh) (function, xshajbfh) (test, jcmj) 

assistant:
It seems the function is performing some operation on each character in the input string. Let's run the function on some upper-case letters and numeric strings to further investigate.

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 0 1 2 3 4 5 6 7 8 9)
user:
Response: Function input - output pairs: (A, g) (B, v) (C, a) (D, l) (E, c) (F, x) (G, u) (H, o) (I, b) (J, t) (K, p) (L, n) (M, w) (N, h) (O, f) (P, q) (Q, k) (R, i) (S, m) (T, j) (U, s) (V, y) (W, r) (X, d) (Y, z) (Z, e) (0, 0) (1, 1) (2, 2) (3, 3) (4, 4) (5, 5) (6, 6) (7, 7) (8, 8) (9, 9) 

assistant:
[DESCRIPTION]: The function appears to be doing a character-wise substitution on the input string, replacing each character with another character according to a fixed pattern. The substitution is case-insensitive and does not affect numbers.

[CODE]:
def approx_function(input_string):
    substitution_dict = {
        'a': 'g', 'b': 'v', 'c': 'a', 'd': 'l', 'e': 'c', 'f': 'x', 'g': 'u',
        'h': 'o', 'i': 'b', 'j': 't', 'k': 'p', 'l': 'n', 'm': 'w', 'n': 'h',
        'o': 'f', 'p': 'q', 'q': 'k', 'r': 'i', 's': 'm', 't': 'j', 'u': 's',
        'v': 'y', 'w': 'r', 'x': 'd', 'y': 'z', 'z': 'e'
    }
    output_string = ""
    for char in input_string:
        if char.isalpha():
            output_string += substitution_dict[char.lower()]
        else:
            output_string += char

    return output_string
