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 the function with some sample inputs.

COMMAND: PYTHON(./temp/function.py "hello" "world" "test" "input" "function")
user:
Response: Function input - output pairs: (hello, acppt) (world, etfpv) (test, kclk) (input, jwuyk) (function, gywxkjtw) 

assistant:
Let's try more inputs to better understand the function:

COMMAND: PYTHON(./temp/function.py "apple" "abcdefgh" "12345" "random" "text")
user:
Response: Function input - output pairs: (apple, quupc) (abcdefgh, qmxvcgra) (12345, 12345) (random, fqwvts) (text, kcik) 

assistant:
Based on the given input-output pairs, it seems like the function is shifting the alphabetical characters in the input strings by a certain number of positions and leaving the numeric characters unchanged. Now let's try to determine the shift value.

COMMAND: PYTHON(./temp/function.py "a" "b" "c" "z" "A" "B" "C" "Z")
user:
Response: Function input - output pairs: (a, q) (b, m) (c, x) (z, o) (A, q) (B, m) (C, x) (Z, o) 

assistant:
The function appears to be shifting the lowercase and uppercase alphabetical characters by 16 positions, wrapping around when it reaches the end of the alphabet, and leaving numeric characters as-is.

[DESCRIPTION]: The function takes a string input and shifts each alphabetical character by 16 positions in the alphabet, wrapping around when necessary. Numeric characters are not altered.

[CODE]:
```python
def approx_function(input_str):
    output_str = ""
    for char in input_str:
        if char.isalpha():
            shift = 16
            if char.islower():
                new_char = chr(((ord(char) - ord('a') + shift) % 26) + ord('a'))
            else:  # char.isupper()
                new_char = chr(((ord(char) - ord('A') + shift) % 26) + ord('A'))
            output_str += new_char
        else:
            output_str += char
    return output_str
```

To validate the description and code, let's test the function with some additional inputs.
COMMAND: PYTHON(./temp/function.py "Caesar" "Cypher" "77Times" "alphaBET23")
