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. 
assistant:
Alright, let's run the function on a few string inputs to understand its behavior. 

COMMAND: PYTHON(./temp/function.py "hello" "world" "test" "function" "12345")
user:
Response: Function input - output pairs: (hello, hellottDw) (world, worldttDw) (test, testttDw) (function, functionttDw) (12345, 12345ttDw) 

assistant:
It seems like the function is appending "ttDw" to the input strings. Let's test with a few more inputs.

COMMAND: PYTHON(./temp/function.py "abcdefgh" "spaces test" "punctuation!" "UPPERCASE")
user:
Response: Function input - output pairs: (abcdefgh, abcdefghttDw) (spaces test, spaces testttDw) (punctuation!, punctuation!ttDw) (UPPERCASE, UPPERCASEttDw) 

assistant:
Based on the input-output pairs, I can conclude that the function simply appends the string "ttDw" to any input string provided.

[DESCRIPTION]: The function takes an input string and appends "ttDw" to it.

[CODE]: 
```python
def f(x):
    return x + "ttDw"
```
