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 the function with some test inputs.

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

assistant:
The function seems to remove all the characters from the input strings. Let's test some more inputs to see if this behavior is consistent.

COMMAND: PYTHON(./temp/function.py "abc" "!@#$" " \t\n" "A1B2C3" "upperCase")
user:
Response: Function input - output pairs: (abc, ) (!@#$, ) ( \t\n, ) (A1B2C3, XYZ) (upperCase, Z) 

assistant:
The function appears to remove all characters except for uppercase letters, which are then replaced by their corresponding position in the alphabet. Let's test a few more inputs to confirm this behavior.

COMMAND: PYTHON(./temp/function.py "Zebra" "AlpHaBet" "ANOTHER" "lowercase" "UPPERCASE")
user:
Response: Function input - output pairs: (Zebra, W) (AlpHaBet, XEY) (ANOTHER, XKLQEBO) (lowercase, ) (UPPERCASE, RMMBOZXPB) 

assistant:
[DESCRIPTION]: The function removes all characters except for uppercase letters. It then replaces the uppercase letters with their corresponding position in the alphabet, where 'A' is replaced by 'X,' 'B' by 'Y,' and so on.

[CODE]: 
```python
def approximate_function(s):
    result = ""
    for char in s:
        if char.isupper():
            result += chr(((ord(char) - ord('A') + 23) % 26) + ord('A'))
    return result
```
