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 on some basic input strings.

COMMAND: PYTHON(./temp/function.py "hello" "world" "test" "123")
user:
Response: Function input - output pairs: (hello, qgeea) (world, cakey) (test, sgis) (123, 123) 

assistant:
Interesting, let's test the function on some more input strings. This time we will test single character strings and empty string.

COMMAND: PYTHON(./temp/function.py "a" "b" "c" "1" " " "")
user:
Response: Function input - output pairs: (a, z) (b, p) (c, o) (1, 1) ( ,  ) (, ) 

assistant:
Let's test the function with some uppercase characters and special characters to see how it behaves.

COMMAND: PYTHON(./temp/function.py "A" "B" "C" "!@#")
user:
Response: Function input - output pairs: (A, z) (B, p) (C, o) (!@#, !@#) 

assistant:
It seems like the function is primarily affecting alphabetic characters. I'd like to test a sequence of lowercase and uppercase alphabetic characters now.

COMMAND: PYTHON(./temp/function.py "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ")
user:
Response: Function input - output pairs: (abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ, zpoyglvnrxnejwadtkisbhcmufzpoyglvqrxnejwadtkisbhcmuf) 

assistant:
Based on the experiments, the function appears to map each character in the input string to another character, leaving other characters unchanged. Lowercase and uppercase letters are both affected but have the same mapping to their respective cases. Specifically, it appears to be a substitution cipher.

[DESCRIPTION]:
The function f(x) is a substitution cipher that takes an input string and maps each letter to another in the same case while leaving other characters, like numbers and special characters, unchanged.

[CODE]:
def approximate_function_f(x):
    lowercase_translation = str.maketrans("abcdefghijklmnopqrstuvwxyz",
                                          "zpoyglvnrxnejwadtkisbhcmuf")
    uppercase_translation = str.maketrans("ABCDEFGHIJKLMNOPQRSTUVWXYZ",
                                          "ZPOYGLVQRXNEJWADTKISBHCMUF")
    return x.translate(lowercase_translation).translate(uppercase_translation)

Please note that this is an approximation of the behavior, and there might be some minor differences.
