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 some initial inputs to get an idea of the function's behavior.

COMMAND: PYTHON(./temp/function.py "hello" "world" "123" "Test" "!@#")
user:
Response: Function input - output pairs: (hello, dneep) (world, xpqeg) (123, 123) (Test, fnhf) (!@#, !@#) 

assistant:
Let's test some more inputs with varying lengths and characters.

COMMAND: PYTHON(./temp/function.py "a" "ab" "abc" "abcd" "abcde" "Python" "qwerty")
user:
Response: Function input - output pairs: (a, w) (ab, wj) (abc, wji) (abcd, wjig) (abcde, wjign) (Python, cvfdpu) (qwerty, axnqfv) 

assistant:
I see a pattern emerging in the outputs. The function seems to shift each character of the input string by a fixed value. Let's test more inputs to confirm our hypothesis.

COMMAND: PYTHON(./temp/function.py "A" "B" "C" "D" "Z" "1" "2" "3" "0" "9")
user:
Response: Function input - output pairs: (A, w) (B, j) (C, i) (D, g) (Z, r) (1, 1) (2, 2) (3, 3) (0, 0) (9, 9) 

assistant:
Based on the results we've gotten so far, the function appears to shift lowercase alphabetic characters by 22 positions forward in the alphabet, wrapping around when necessary. For uppercase alphabetic characters, the function seems to always output their lowercase counterpart. Lastly, the function appears to leave numeric and non-alphabetic characters unchanged.

[DESCRIPTION]: The function shifts lowercase alphabetic characters in the input string by 22 positions forward in the alphabet while wrapping around and converts uppercase alphabetic characters to their lowercase equivalents. Numeric and non-alphabetic characters remain unchanged.

[CODE]: 
```python
def approximate_function(input_str):
    result_str = ""
    for char in input_str:
        if char.isupper():
            result_str += char.lower()
        elif char.islower():
            result_str += chr(((ord(char) - ord('a') + 22) % 26) + ord('a'))
        else:
            result_str += char
    return result_str
```
