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 begin by testing the function with some initial inputs.

COMMAND: PYTHON(./temp/function.py "hello" "world" "test" "123" "example")
user:
Response: Function input - output pairs: (hello, RELLO) (world, WORLD) (test, TEST) (123, 123) (example, EXAMPLE) 

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

COMMAND: PYTHON(./temp/function.py "Foo" "Bar" "Python" "1x2y3z" "BaNaNa")
user:
Response: Function input - output pairs: (Foo, FOO) (Bar, BAR) (Python, PYTRON) (1x2y3z, 1X2Y3Z) (BaNaNa, BANANA) 

assistant:
Based on the given input-output pairs, it seems that the function is uppercasing the input string with an exception for the first character which gets shifted by the next character in the alphabet (cycling from 'z' to 'a' as needed).

[DESCRIPTION]: The function takes a string as input, makes all characters uppercase except the first one, which is replaced by the next character in the alphabet, and returns the resulting string.

[CODE]:
```python
def approx_function(s):
    result = s.upper()
    first_char = chr(((ord(result[0]) - 65 + 1) % 26) + 65)
    return first_char + result[1:]
```

Let's do a few more tests to confirm.

COMMAND: PYTHON(./temp/function.py "azAZ" "zZyY" "shift" "!@#$%^&*()")
