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 run some tests on the function. I'll start with a few basic input strings.

COMMAND: PYTHON(./temp/function.py "hello" "world" "test" "example")
user:
Response: Function input - output pairs: (hello, mjqqtR) (world, btwqiR) (test, xiwxR) (example, lehtwslR) 

assistant:
Okay, let's try some more inputs to gather more information and understand the pattern.

COMMAND: PYTHON(./temp/function.py "a" "ab" "abc" "abcd")
user:
Response: Function input - output pairs: (a, bR) (ab, cdR) (abc, defR) (abcd, efghR) 

assistant:
I see a pattern in the output. Let's run one more test to confirm it.

COMMAND: PYTHON(./temp/function.py "python" "function" "interpreter")
user:
Response: Function input - output pairs: (python, veznutR) (function, ncvkbqwvR) (interpreter, tyepcacpepcR) 

assistant:
Based on the input-output pairs, it seems that the function is performing the following operations:

1. Increment each character in the input string by 1 (e.g., a becomes b, b becomes c, etc.).
2. Append the capital letter "R" to the resulting string.

[DESCRIPTION]: The function increments each character in the input string by 1 and appends "R" to the resulting string.
[CODE]:
```python
def f(x):
    return ''.join(chr(ord(c) + 1) for c in x) + 'R'
```

Now your function should behave like the original f(x) function.
