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 testing the function with some simple inputs.

COMMAND: PYTHON(./temp/function.py a b c 1 2 3)
user:
Response: Function input - output pairs: (a, Ta) (b, Tb) (c, Tc) (1, T1) (2, T2) (3, T3) 

assistant:
Let's test the function with longer strings, special characters, and mixed cases.

COMMAND: PYTHON(./temp/function.py "Hello world" "123456" "qwerty" "Python%!")
user:
Response: Function input - output pairs: (Hello world, HelloT world) (123456, 123Z456) (qwerty, qweZrty) (Python%!, PythZon%!) 

assistant:
The function seems to be performing an operation, specifically inserting a character at a specific position in the input string. I will need more data points to understand the exact pattern. 

Let's try few more test inputs, including some edge cases:

COMMAND: PYTHON(./temp/function.py "Test" "function" "interpreter" "edge cases" "")
user:
Response: Function input - output pairs: (Test, TeZst) (function, funcZtion) (interpreter, interTpreter) (edge cases, edge Zcases) (, T) 

assistant:
[DESCRIPTION]: The function inserts a character based on the first character of the input string. If the first character is a vowel, it inserts the letter 'T' after the first character. If the input starts with a consonant, it inserts the letter 'Z' after the first character. If the input string is empty, it returns 'T'. 

[CODE]:
```python
def custom_function(s):
    if s == "":
        return 'T'
    elif s[0].lower() in "aeiou":
        return s[:1] + 'T' + s[1:]
    else:
        return s[:1] + 'Z' + s[1:]
```

Please note that this approximation may not cover all possible cases, but it describes most of the function behavior based on our tests.
