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 f(x) on some example inputs. 

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, H) (B, I) (C, J) (D, K) (E, L) (F, M) (G, N) (H, O) (I, P) (J, Q) (K, R) (L, S) (M, T) (N, U) (O, V) (P, W) (Q, X) (R, Y) (S, Z) (T, A) (U, B) (V, C) (W, D) (X, E) (Y, F) (Z, G) 

assistant:
It seems that for each uppercase letter, the function shifts the input to the right by a certain number of positions in the alphabet. Let's test this hypothesis with lowercase letters.

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, ) (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, ) 

assistant:
It appears that the function only processes uppercase letters by shifting them to the right in the alphabet. Lowercase letters return an empty output. Let's further test the function with numbers, symbols, and a mix of characters.

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

assistant:
Based on the input-output pairs, the function appears to shift uppercase letters to the right in the alphabet by a certain number of positions (7 in this case) while ignoring other characters. Here's the description and the approximation of the f(x) behavior:

[DESCRIPTION]: The function takes a string input and returns a new string in which uppercase letters are shifted 7 positions to the right in the alphabet, wrapping around at 'Z'. All other characters, including lowercase letters, return an unchanged output or an empty output depending on the input character.

[CODE]:
```python
def shift_uppercase(input_str):
    output_str = ''
    for char in input_str:
        if 'A' <= char <= 'Z':
            output_str += chr(((ord(char) - ord('A') + 7) % 26) + ord('A'))
        else:
            output_str += char
    return output_str
```
