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, I'll start by testing the function with a few inputs. 

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

assistant:
Thank you for the response. I will test more inputs to understand the function better.

COMMAND: PYTHON(./temp/function.py "example" "change" "tree" "house" "function")
user:
Response: Function input - output pairs: (example, example) (change, change) (tree, tree) (house, house) (function, function) 

assistant:
It seems like the function is mostly returning the input string unchanged. I would like to test more inputs, especially strings containing "b", as the previous test changed "abc" to "avc".

COMMAND: PYTHON(./temp/function.py "baby" "bubble" "robot" "abba" "alphabet")
user:
Response: Function input - output pairs: (baby, vavy) (bubble, vuvvle) (robot, rovot) (abba, avva) (alphabet, alphavet) 

assistant:
[DESCRIPTION]: The function seems to replace all occurrences of the letter "b" in the input string with the letter "v".

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

Let's test a few more inputs to make sure the approximation holds. 

COMMAND: PYTHON(./temp/function.py "bobcat" "batman" "rabbit" "foobar")
