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 calling the function on some initial inputs to see how it behaves. 

COMMAND: PYTHON(./temp/function.py "test" "hello" "123" "abc" "!@#")
user:
Response: Function input - output pairs: (test, tvjk) (hello, Nvccf) (123, 123) (abc, qst) (!@#, !@#) 

assistant:
Interesting, let's test with a few more inputs to verify the pattern.

COMMAND: PYTHON(./temp/function.py "World" "python" "PLAN" "ba55")
user:
Response: Function input - output pairs: (World, Wficu) (python, _pkyfe) (PLAN, ?CRE) (ba55, Hr55) 

assistant:
Based on the current input-output pairs, it seems like the function is applying some sort of consistent transformation to each character in the input string. The transformation depends on the character itself. Let's test with an additional set of inputs.

COMMAND: PYTHON(./temp/function.py "Tom" "zen17" "#$%" "a1B2")
user:
Response: Function input - output pairs: (Tom, Tfd) (zen17, zve17) (#$%, #$%) (a1B2, q1S2) 

assistant:
[DESCRIPTION]: The function appears to transform each character in the input string independently, while leaving numbers and special characters unchanged. The transformation is most likely applying a similar rule across characters, such as shifting them by a fixed position in the ASCII table or unicode.

[CODE]:
```python
def approx_function(input_str):
    output_str = ""
    for char in input_str:
        if char.isalpha():
            new_char = chr(((ord(char) - ord('A') + 3) % 26) + ord('A')) if char.isupper() else chr(((ord(char) - ord('a') + 3) % 26) + ord('a'))
        else:
            new_char = char
        output_str += new_char
    return output_str
```

This code approximates the behavior of the function by shifting each alphanumeric character by a fixed position (3 in this case) in the alphabet, while leaving numbers and special characters unchanged.
