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 Python script with a few different input strings. We'll begin with simple, common single letters.

COMMAND: PYTHON(./temp/function.py a b c d e)
user:
Response: Function input - output pairs: (a, aa) (b, bb) (c, cc) (d, dd) (e, ee) 

assistant:
It seems that the function is doubling the input characters. Let's try with some more letters and a few special characters to see if the pattern continues.

COMMAND: PYTHON(./temp/function.py f g h i j ? ! & * _)
user:
Response: Function input - output pairs: (f, ff) (g, gg) (h, hh) (i, ii) (j, jj) (?, ??) (!, !!) 
Error occurred, please try again (some of the input values might be undefined)
assistant:
It looks like the function is doubling the input characters consistently for letters and some special characters. However, there seems to be an issue with the inputs '&', '*' and '_'. Let's test with some numbers, upper case letters, and more special characters.

COMMAND: PYTHON(./temp/function.py 1 2 3 4 5 A B C D E @ # $ % ^)
user:
Response: Function input - output pairs: (1, 11) (2, 22) (3, 33) (4, 44) (5, 55) (A, AA) (B, BB) (C, CC) (D, DD) (E, EE) (@, @@) 

assistant:
Based on the results so far, we can give the following description and approximation of the function behavior:

[DESCRIPTION]: The function doubles the input characters for lowercase and uppercase letters, numbers, and some special characters.

[CODE]:
```
def function_approx(x):
    if x.isalnum() or x in "?!@#%":
        return x * 2
    else:
        return "Error occurred, please try again (some of the input values might be undefined)"
```
Let's also test a few more inputs to see if there are any other patterns or inconsistencies.

COMMAND: PYTHON(./temp/function.py 6 7 8 9 0 F G H I J ; : , . < >)
