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 a few initial tests to gather some information about f(x).

COMMAND: PYTHON(./temp/function.py "a" "b" "c" "abc" "hello" "world")
user:
Response: Function input - output pairs: (a, aTa) (b, bTb) (c, cTc) (abc, abTcb) (hello, helTlol) (world, worTldr) 

assistant:
It seems like the function is inserting a "T" in the middle of the input strings. Let's run a few more tests with different inputs to confirm the hypothesis.

COMMAND: PYTHON(./temp/function.py "example" "test" "12345" "qwerty" "AI")
user:
Response: Function input - output pairs: (example, examTplem) (test, teTsts) (12345, 123T453) (qwerty, qweTrtyr) (AI, ATII) 

assistant:
Based on the input-output pairs we have so far, I can conclude that the function's behavior is as follows:

1. Insert a "T" in the middle of the input string.
2. Repeat the second half of the input string right after the "T".

Here's a simple Python code implementation that approximates the behavior of f(x):

[DESCRIPTION]: The function inserts a "T" in the middle of the input string and then repeats the second half of the input string right after the "T".

[CODE]:
```python
def f_approx(x):
    middle = len(x) // 2
    return x[:middle] + "T" + x[middle:] + x[middle:]
```
Let's test some more cases to ensure the description and code accurately represent the function's behavior.

COMMAND: PYTHON(./temp/function.py "banana" "empty" "function" "python" "commands")
