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 begin by testing the function f(x) on a few different string inputs.

COMMAND: PYTHON(./temp/function.py "hello" "world" "123" "example" "test")
user:
Response: Function input - output pairs: (hello, HELLOdB) (world, WORLDdB) (123, 123dB) (example, EXAMPLEdB) (test, TESTdB) 

assistant:
It seems like the function f(x) is converting the input string to uppercase and appending 'dB' at the end.

[DESCRIPTION]: The function takes a string input, converts it to uppercase, and appends 'dB' to the end of it.

[CODE]:
```python
def f(x):
    return x.upper() + 'dB'
```
Let's test on some more inputs to make sure our understanding is correct.

COMMAND: PYTHON(./temp/function.py "apple" "BANANA" "mIxEd" "123abc" "spac es")
