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.

Let's start by experimentally testing the f(x) function with some inputs. 

COMMAND: PYTHON(./temp/function.py "hello" "abc" "test" "123")
user:
Response: Function input - output pairs: (hello, heLllo) (abc, aLbc) (test, teLst) (123, 1L23) 

assistant:
Interesting. Let's try some more inputs.

COMMAND: PYTHON(./temp/function.py "world" "example" "function" "test123")
user:
Response: Function input - output pairs: (world, woLrld) (example, exaLmple) (function, funcLtion) (test123, tesLt123) 

assistant:
Thank you for the data. Let's try some more inputs, this time with special characters, single characters, and an empty string.

COMMAND: PYTHON(./temp/function.py "!" "a" " " "")
user:
Response: Function input - output pairs: (!, L!) (a, La) ( , L ) (, L) 

assistant:
Based on the data observed, it seems that the function inserts the letter 'L' after a specified position in the input string.

[DESCRIPTION]: The function inserts the letter 'L' after the 2nd character in the input string.

[CODE]: 
```python
def insert_L(input_string):
    return input_string[:2] + 'L' + input_string[2:]
```
Let's test if this hypothesis holds with more varied inputs.

COMMAND: PYTHON(./temp/function.py "test_cases" "insertHere" "p@ssw0rd" "h#ll0")
