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's start by running some experiments on the function with different string inputs. 

COMMAND: PYTHON(./temp/function.py "hello" "world" "test" "123" "abc")
user:
Response: Function input - output pairs: (hello, hullv) (world, wvrld) (test, tust) (123, 123) (abc, vbc) 

assistant:
Thank you for providing the output. Let's run more tests to better understand the function.

COMMAND: PYTHON(./temp/function.py "abcdefg" "hijklmnop" "qrstuvwxyz" "!@#$%^&*" "()" "PROGRAM")
user:
Response: Function input - output pairs: (abcdefg, vbadvfg) (hijklmnop, hvjhlmnvp) (qrstuvwxyz, qqstvvwxyz) (!@#$%^&*, !@#$%^&*) ((), ()) (PROGRAM, PRtGRvM) 

assistant:
Thank you for the output. The function seems to have a certain pattern when modifying the input strings. Let's run a few more tests to help understand this pattern better.

COMMAND: PYTHON(./temp/function.py "snake" "Python" "Assistant" "text" "General")
user:
Response: Function input - output pairs: (snake, snvhv) (Python, Pythvn) (Assistant, vsssstvnt) (text, tvxt) (General, Gvnvrvl) 

assistant:
Based on the input-output pairs, the function appears to replace certain characters, e.g., 'a' is replaced with 'v', 'e' with 'v', 'i' with 'v', 'o' with 'v', and 'u' with 'v'. However, it doesn't modify numbers, special characters, or parentheses.

[DESCRIPTION]: The function replaces vowels ('a', 'e', 'i', 'o', and 'u') in the input string with the letter 'v'. It doesn't modify numbers, special characters, or parentheses.

[CODE]:
```python
def approx_function(s: str) -> str:
    vowels = 'aeiouAEIOU'
    result = ""
    for char in s:
        result += 'v' if char in vowels else char
    return result
```

Let's run one more test to confirm our understanding of the function.

COMMAND: PYTHON(./temp/function.py "Various" "Characters" "In" "This" "Input")
