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. 
assistant:
Alright, I will start by calling the function with a few initial inputs. 

COMMAND: PYTHON(./temp/function.py "hello" "world" "python" "123" "test")
user:
Response: Function input - output pairs: (hello, hellgl) (world, worl\r) (python, pythofh) (123, 1232) (test, tesls) 

assistant:
Thank you for the response. I will continue to investigate the function with more input strings.

COMMAND: PYTHON(./temp/function.py "apple" "banana" "AbCdEfG" "Function" "2019" "Example")
user:
Response: Function input - output pairs: (apple, appl]p) (banana, bananza) (AbCdEfG, AbCdEf?d) (Function, Functioft) (2019, 20191) (Example, Exampl]m) 

assistant:
Thank you. I will run one more set of inputs to gain more insights about the function behavior.

COMMAND: PYTHON(./temp/function.py "AI" "Daphne" "interesting" "happiness" "Zebra" "Empty")
user:
Response: Function input - output pairs: (AI, AAA) (Daphne, Daphn]h) (interesting, interestin_e) (happiness, happineski) (Zebra, Zebrzb) (Empty, Emptqp) 

assistant:
[DESCRIPTION]: The function seems to be replacing the last character of the input string with the ASCII character that is two positions after the original last character. In addition, the function appends the ASCII character that is two positions before the original last character to the end of the string.

[CODE]:
```python
def approximated_function(input_string):
    if len(input_string) > 0:
        last_char = input_string[-1]
        new_last_char = chr(ord(last_char) + 2)
        appended_char = chr(ord(last_char) - 2)
        return input_string[:-1] + new_last_char + appended_char
    else:
        return input_string
```
