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.

Let's start by running f(x) on a few input strings to see the output and understand the behavior of the function. 

COMMAND: PYTHON(./temp/function.py "hello" "world" "Python" "123" "!@#")
user:
Response: Function input - output pairs: (hello, helloGOBo) (world, worldGOBo) (Python, PythnoGOBo) (123, 123GOBo) (!@#, !@#GOBo) 

assistant:
It seems that the function is appending the string "GOBo" to the end of the input string. Let's test with a few more examples to confirm this behavior.

COMMAND: PYTHON(./temp/function.py "apple" "banana" "TEST" "example123" "Sample@!")
user:
Response: Function input - output pairs: (apple, appleGOBo) (banana, banaanGOBo) (TEST, TESTGOBo) (example123, examlpe123GOBo) (Sample@!, Sampel@!GOBo) 

assistant:
Based on the outputs, the function seems to not only append "GOBo" to the input string but also swap the second and third characters of the input string. I will now provide a description and an approximation of the function's behavior in Python code.

[DESCRIPTION]: The function takes an input string, swaps the second and third characters, and appends "GOBo" to the end of the modified string.

[CODE]:
```python
def approx_function(input_str):
    input_str = list(input_str)
    if len(input_str) >= 3:
        input_str[1], input_str[2] = input_str[2], input_str[1]
    return ''.join(input_str) + "GOBo"
```

To further confirm its behavior, we can run more test cases.

COMMAND: PYTHON(./temp/function.py "ABCD" "abcdef" "1a2b3c" "x4yz8" "-=>")
