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 me test the function with some example inputs. 

COMMAND: PYTHON(./temp/function.py "hello" "world" "123" "testing" "!@#")
user:
Response: Function input - output pairs: (hello, dfllo) (world, sprld) (123, 123) (testing, peuting) (!@#, !@#) 

assistant:
Interesting. I will test the function with more inputs.

COMMAND: PYTHON(./temp/function.py "abcdefghijklmnopqrstuvwxyz" "ABCDEFGHIJKLMNOPQRSTUVWXYZ" "100" "this is a sentence" "PYTHON")
user:
Response: Function input - output pairs: (abcdefghijklmnopqrstuvwxyz, zbcdefghijulmnopqrstuvwxyz) (ABCDEFGHIJKLMNOPQRSTUVWXYZ, ZBCDEFGHIJKLMNOPQRSTUVWXYY) (100, 100) (this is a sentence, piis is a sentence) (PYTHON, LYTKON) 

assistant:
Based on the inputs and outputs, I can observe a specific behavior in the function. Here's my description and approximation of the function's behavior.

[DESCRIPTION]: The function takes a string input and iterates through the characters. If the character is a lowercase or uppercase letter (not a digit or special character), it replaces the character with the next letter in the alphabetic order. If the character is the last letter in the alphabet, whether lowercase 'z' or uppercase 'Z', it remains unchanged.

[CODE]: 
```python
def approx_function(s):
    result = ''
    for c in s:
        if c == 'z' or c == 'Z':
            result += c
        elif c.isalpha():
            result += chr(ord(c) + 1)
        else:
            result += c
    return result
```

I will now test this function with more inputs to verify its behavior.

COMMAND: PYTHON(./temp/function.py "compute" "APPLE" "banana99" "Example2021" "*&^%")
