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.

Let's start by running a few experiments on the function f(x).

COMMAND: PYTHON(./temp/function.py "hello" "world" "test" "function")
user:
Response: Function input - output pairs: (hello, lhkku) (world, cumkf) (test, ahda) (function, jxpearup) 

assistant:
It seems like there's some character transformation taking place. Let's test a few more examples to find a pattern.

COMMAND: PYTHON(./temp/function.py "abc" "def" "ghi" "alphabet")
user:
Response: Function input - output pairs: (abc, zge) (def, fhj) (ghi, blr) (alphabet, zknlzgha) 

assistant:
From the outputs, it seems as if there is a pattern of some character shifts. Let's test single characters to understand better.

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

assistant:
[DESCRIPTION]: The function f(x) appears to shift each character in the input string to a different character according to the following mapping:

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

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