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 on some basic inputs to get an idea of its behavior. I'll start with some single-letter strings and an empty string.

COMMAND: PYTHON(./temp/function.py a b c "" 1 2 3)
user:
Response: Function input - output pairs: (a, aCKUgv) (b, bCKUgv) (c, cCKUgv) (, CKUgv) (1, 1CKUgv) (2, 2CKUgv) (3, 3CKUgv) 

assistant:
It seems that the function appends the string "CKUgv" to the input string. Let's test with some longer strings and special characters to see if this pattern holds.

COMMAND: PYTHON(./temp/function.py hello world !@#$)
user:
Response: Function input - output pairs: (hello, helloCKUgv) (world, worldCKUgv) (!@#$, !@#$CKUgv) 

assistant:
Based on the input-output pairs, the function appears to simply append the string "CKUgv" to the given input string.

[DESCRIPTION]: The function takes a string input and appends the string "CKUgv" to it.

[CODE]:
```python
def approximate_function(input_string):
    return input_string + "CKUgv"
```
