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 with a few example inputs. 

COMMAND: PYTHON(./temp/function.py "hello" "world" "test123" "another_string" "example")
user:
Response: Function input - output pairs: (hello, zwwps) (world, ucifn) (test123, 321xwix) (another_string, ovqzba_zmpbwvi) (example, taebpmt) 

assistant:
Let's test some more inputs, including single characters, special characters, and empty strings.

COMMAND: PYTHON(./temp/function.py "a" "b" "c" "1" "2" "3" "@" "#" "$" " " "")
user:
Response: Function input - output pairs: (a, a) (b, b) (c, c) (1, 1) (2, 2) (3, 3) (@, @) (#, #) ($, $) ( ,  ) (, ) 

assistant:
Based on the current responses, it seems like the function might be performing different transformations for letters and digits. Let's test more letter and digit combinations to see if a pattern emerges.

COMMAND: PYTHON(./temp/function.py "abc" "def" "ghi" "789" "mnop" "qrst" "uvwxyz")
user:
Response: Function input - output pairs: (abc, cba) (def, ihg) (ghi, onm) (789, 987) (mnop, cbaz) (qrst, kjih) (uvwxyz, wvutsr) 

assistant:
Based on the test cases so far, it seems that the function behaves differently for letters and digits. 

For letters, it seems to apply a Caesar cipher-like transformation, shifting letters in the alphabet. However, this transformation seems to be distance-based, with the first letter of the alphabet shifted to the third position, the second to the fourth, and so on. For digits, the function just reverses the order. In all cases, special characters and spaces are not transformed.

[DESCRIPTION]: The function takes a string input and applies a Caesar cipher-like transformation to the letters, shifting each letter by a distance-based value in the alphabet (e.g., 'a' goes to 'c', 'b' goes to 'd', etc.). Digits in the input string are reversed in order, and special characters and spaces remain unchanged.

[CODE]:
```python
def approx_function(s):
    result = []

    for c in s:
        if c.isalpha():
            shifted_c = chr(((ord(c) - ord('a') + 2) % 26) + ord('a'))
            result.append(shifted_c)
        elif c.isdigit():
            result.insert(0, c)
        else:
            result.append(c)

    return ''.join(result)
```

Let's test the function with more inputs before wrapping up.

COMMAND: PYTHON(./temp/function.py "Coding" "Cipher" "Task" "1234" "!@#")
