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.

To get started, let's call the function f(x) on a few input strings.

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

assistant:
It seems like the function f(x) is returning the same string as the input. Let's test with some more strings to be sure.

COMMAND: PYTHON(./temp/function.py "test" "123" "!@#")
user:
Response: Function input - output pairs: (test, test) (123, 123) (!@#, !@#) 

assistant:
It appears that f(x) simply returns the same input string without any modification. Here's a description and a code approximation of the function.

[DESCRIPTION]: The function f(x) takes a string input and returns the same string without any modifications.

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