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.

I understand, let's start by testing the function with various inputs.

COMMAND: PYTHON(./temp/function.py "hello" "world" "123" "test" "&*^!@")
user:
Response: Function input - output pairs: (hello, hTllo) (world, world) (123, 123) (test, tTst) (&*^!@, &*^!@) 

assistant:
Thank you. Let's test some more inputs to figure this function out.

COMMAND: PYTHON(./temp/function.py "apple" "banana" "function" "AiAssistant" "sample")
user:
Response: Function input - output pairs: (apple, applT) (banana, banana) (function, function) (AiAssistant, AiAssistant) (sample, samplT) 

assistant:
It seems that the function might be replacing or inserting a character 'T' in the input string.

Let's test more inputs to confirm the behavior.

COMMAND: PYTHON(./temp/function.py "replace" "insert" "pattern" "finding" "formation")
user:
Response: Function input - output pairs: (replace, rTplacT) (insert, insTrt) (pattern, pattTrn) (finding, finding) (formation, formation) 

assistant:
Based on the results, it appears that the function inserts a 'T' before every 'e' character in the input string.

[DESCRIPTION]: The function inserts a 'T' before every occurrence of the letter 'e' in the input string.

[CODE]:

```python
def approximate_function(s: str) -> str:
    return s.replace("e", "Te")
```
