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.

Great! Let's start by running the function with some different inputs to get an idea of its behavior. 

COMMAND: PYTHON(./temp/function.py "test" "hello" "world" "123" "abc")
user:
Response: Function input - output pairs: (test, TEST) (hello, TQXXA) (world, TLOIA) (123, 123) (abc, ABC) 

assistant:
Let's test the function with additional inputs to further analyze its behavior.

COMMAND: PYTHON(./temp/function.py "example" "function" "test123" "qwerty" "HELLO")
user:
Response: Function input - output pairs: (example, PILXAWP) (function, MBUJAPVU) (test123, PAOP123) (qwerty, XDLYAF) (HELLO, TQXXA) 

assistant:
The function seems to do some transformations on the input strings. Let's try some more inputs, including inputs with special characters and spaces.

COMMAND: PYTHON(./temp/function.py "abcd" "ABC1" "!@#$" " " "mixED")
user:
Response: Function input - output pairs: (abcd, ABCD) (ABC1, ABC1) (!@#$, !@#$) ( ,  ) (mixED, JFUBA) 

assistant:
[DESCRIPTION]: The function seems to modify the input string in several ways, such as capitalizing lowercase letters, shifting vowels by a certain number of positions in the alphabet, and keeping numbers and special characters unchanged.

[CODE]: 

```python
def approx_function(s):
    vowels = 'AEIOU'
    result = ''
    for char in s:
        if char.islower():
            char = char.upper()
        if char in vowels:
            char = chr(ord(char) + 4)
            if char > 'Z':
                char = chr(ord(char) - 26)
        result += char
    return result
```
