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. 
assistant:
Alright, let's start by testing the function with some initial inputs to understand its behavior.

COMMAND: PYTHON(./temp/function.py "test" "hello" "world")
user:
Response: Function input - output pairs: (test, testH) (hello, helloH) (world, worldH) 

assistant:
It seems the function is appending 'H' at the end of the input strings. Let's verify this behavior with few more inputs.

COMMAND: PYTHON(./temp/function.py "abc" "123" "!@#")
user:
Response: Function input - output pairs: (abc, abcH) (123, 123H) (!@#, !@#H) 

assistant:
Based on the results, I can provide the following description and code for the function f(x):

[DESCRIPTION]: The function takes a string input and appends 'H' at the end of it.

[CODE]: 
```python
def f(x):
    return x + 'H'
```

Let me know if you need more tests or a different description.
