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 the function with some basic string inputs to see the output.

COMMAND: PYTHON(./temp/function.py "hello" "world" "test" "example")
user:
Response: Function input - output pairs: (hello, HELLO) (world, WORLD) (test, TEST) (example, EXAMPLE) 

assistant:
It appears that the function is converting the input string to uppercase. Let's test it with a few more cases to confirm.

COMMAND: PYTHON(./temp/function.py "Input" "Function" "CaMel" "mIxEd")
user:
Response: Function input - output pairs: (Input, INPUT) (Function, FUNCTION) (CaMel, CAMEL) (mIxEd, MIXED) 

assistant:
Based on the results, it seems the function is converting the input string to uppercase. Here's a description and code of the implemented function:

[DESCRIPTION]: The function takes a string input and returns the uppercase equivalent of the input string.
[CODE]: 
```python
def f(x):
    return x.upper()
```
