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.

Alright, let's start by testing the function with some example inputs. 

COMMAND: PYTHON(./temp/function.py "Hello" "world" "12345" "test" "function")
user:
Response: Function input - output pairs: (Hello, mqssb) (world, jbxso) (12345, 12345) (test, eque) (function, izwredbw) 

assistant:
Thank you for the response. Let's try some more inputs.

COMMAND: PYTHON(./temp/function.py "A" "B" "C" "xyZ" "mNo")
user:
Response: Function input - output pairs: (A, t) (B, f) (C, r) (xyZ, lky) (mNo, hwb) 

assistant:
It seems like some alphabetical transformation is happening. Let's test more examples.

COMMAND: PYTHON(./temp/function.py "abc" "def" "ghi" "jkl" "mnopqrstuvwxyz")
user:
Response: Function input - output pairs: (abc, tfr) (def, oqi) (ghi, pmd) (jkl, cns) (mnopqrstuvwxyz, hwbavxuezgjlky) 

assistant:
Based on the input-output pairs, it appears that the function is performing an alphabetical transformation, where each character in the input string is transformed into a new character by shifting a certain distance in the alphabet. It also seems to preserve digits without any transformation.

[DESCRIPTION]: The function takes a string input and performs a Caesar-like alphabetic shift on each character in the string, with the exception of digits, which are preserved as-is. The function appears to shift the characters by a fixed distance.

[CODE]:
```python
def Caesar_shift(input_string, shift):
    output_string = ""
    for ch in input_string:
        if ch.isalpha():
            shift_by = shift % 26
            if ch.isupper():
                output_string += chr((ord(ch) - ord('A') + shift_by) % 26 + ord('A'))
            else:
                output_string += chr((ord(ch) - ord('a') + shift_by) % 26 + ord('a'))
        elif ch.isdigit():
            output_string += ch
        else:
            output_string += ch
    return output_string
```

We should determine the shift distance used by the function:

COMMAND: PYTHON(./temp/function.py "a" "b" "c" "A" "B" "C")
