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.

I will start by calling the function with different inputs to understand its behavior. 

COMMAND: PYTHON(./temp/function.py "a" "ab" "abc" "123" "12a" "!@$")
user:
Response: Function input - output pairs: (a, uc) (ab, cud) (abc, cude) (123, 1u23) (12a, 1u2c) (!@$, !u@$) 

assistant:
I see some patterns in the output. I will run more tests to further understand the function's behavior.

COMMAND: PYTHON(./temp/function.py "hello" "world" "computer" "testing" "alternative")
user:
Response: Function input - output pairs: (hello, jgunnq) (world, yqutnf) (computer, eqoruwvgt) (testing, vguuvkpi) (alternative, cnvgtupcvkxg) 

assistant:
I have noticed that the given function modifies the input string and seems to change characters based on some rules. I will run a more specific tests to better understand the behavior.

COMMAND: PYTHON(./temp/function.py "abcdefghijklm" "nopqrstuvwxyz" "ABCDEFGHIJKLMNOPQRSTUVWXYZ" "0123456789")
user:
Response: Function input - output pairs: (abcdefghijklm, cdefghuijklmno) (nopqrstuvwxyz, pqrstuuvwxyzab) (ABCDEFGHIJKLMNOPQRSTUVWXYZ, CDEFGHIJKLMNOuPQRSTUVWXYZAB) (0123456789, 01234u56789) 

assistant:
[DESCRIPTION]: The function modifies the input string by incrementing ASCII value of each character by 2 and inserting a 'u' after 5th character.

[CODE]:
```python
def approx_function(input_string):
    output = []
    for i, char in enumerate(input_string):
        output.append(chr(ord(char) + 2))
        if i == 4:
            output.append('u')
    return ''.join(output)
```
Please note that this implementation is only an approximation of the original function and might not cover all scenarios, but it should work for most cases.
