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 input strings to get an idea of what it does.

COMMAND: PYTHON(./temp/function.py "hello" "world" "test" "example" "123")
user:
Response: Function input - output pairs: (hello, hellotB) (world, worldtB) (test, testtB) (example, exampletB) (123, 123tB) 

assistant:
It appears that the function appends "tB" at the end of the input strings. Let's test more inputs to confirm this behavior.

COMMAND: PYTHON(./temp/function.py "abcdef" "Python" "input" "Lorum" "Ipsum")
user:
Response: Function input - output pairs: (abcdef, abcdeftB) (Python, PythontB) (input, inputtB) (Lorum, LorumtB) (Ipsum, IpsumtB) 

assistant:
Based on the input and output pairs so far, the function seems to append "tB" at the end of the input strings. Here is the description and approximation of the function:

[DESCRIPTION]: The function appends 'tB' at the end of the input string.

[CODE]:
```python
def f(x):
    return x + 'tB'
```

If you would like more tests to be run, please let me know.
