Hi, your job is to interpret a function f(x) that is implemented in the ./temp0/function.py script. f(x) takes string inputs.
All you can do is call f(x) on an input string by running PYTHON(./temp0/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(./temp0/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.

To describe the function implemented by f(x), I will run experiments on it using a range of inputs.

COMMAND: PYTHON(./temp0/function.py "a")
Response: Response: None

COMMAND: PYTHON(./temp0/function.py "123")
Response: Response: "321"

COMMAND: PYTHON(./temp0/function.py "word")
Response: Response: "drow"

COMMAND: PYTHON(./temp0/function.py "hello world")
Response: Response: "dlrow olleh"

Based on the experiments, I can describe the function as one that reverses the order of characters in a given string.

[DESCRIPTION]: The function reverses the order of characters in a given string.
[CODE]: Code that approximates the behavior of the function:

def reverse_string(string):
    return string[::-1]
