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 running a couple of experiments with different string inputs to understand the function's behavior.

COMMAND: PYTHON(./temp/function.py "hello" "world" "test" "python" "12345")
user:
Response: Function input - output pairs: (hello, hevvo) (world, worvd) (test, test) (python, python) (12345, 12345) 

assistant:
It seems that the function may be altering some characters in the input string. Let's try a few more experiments with different inputs to identify a pattern.

COMMAND: PYTHON(./temp/function.py "abcdefghijk" "uvwxyz" "lmnopqrst" "AAAABBBBCCCC" "ZzYyXxWw")
user:
Response: Function input - output pairs: (abcdefghijk, abcdefghijk) (uvwxyz, uvwxyz) (lmnopqrst, vmnopqrst) (AAAABBBBCCCC, AAAABBBBCCCC) (ZzYyXxWw, ZzYyXxWw) 

assistant:
Based on the current input-output pairs, it seems that the function is replacing some specific characters in the input string. Let's run a specific test with the alphabet in both lowercase and uppercase to see if we can identify a more apparent pattern.

COMMAND: PYTHON(./temp/function.py "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ")
user:
Response: Function input - output pairs: (abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ, abcdefghijkvmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ) 

assistant:
The function appears to replace the character 'l' with 'v' in the input string. Let's verify this with some more examples containing the character 'l' and other characters.

COMMAND: PYTHON(./temp/function.py "hello" "world" "example" "lovely" "parallel")
user:
Response: Function input - output pairs: (hello, hevvo) (world, worvd) (example, exampve) (lovely, vovevy) (parallel, paravvev) 

assistant:
[DESCRIPTION]: The function replaces the character 'l' with 'v' in the input string.

[CODE]:
```python
def approx_function(input_string):
    return input_string.replace("l", "v")
```
