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 basic inputs. 

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

assistant:
It seems like it replaces some characters in the input string with others. Let's test with some more inputs to see the pattern.

COMMAND: PYTHON(./temp/function.py "abcdefghijklmnopqrstuvwxyz" "ABCDEFGHIJKLMNOPQRSTUVWXYZ" "!@#$%^&*()_+" "0123456789")
user:
Response: Function input - output pairs: (abcdefghijklmnopqrstuvwxyz, abldefghijklmnopqrstuvwxyz) (ABCDEFGHIJKLMNOPQRSTUVWXYZ, ABCDEFGHIJKLMNOPQRSTUVWXYZ) (!@#$%^&*()_+, !@#$%^&*()_+) (0123456789, 0123456789) 

assistant:
[DESCRIPTION]: It appears that the function replaces some characters in the input strings with another character. In the tests performed, the letter 'c' is replaced with 'l' and 'r' is replaced with 'k'. All other characters remain unchanged.

[CODE]:

```python
def approx_function(input_str):
    return input_str.replace('c', 'l').replace('r', 'k')
```
Let's perform a few more tests to confirm this behavior.

COMMAND: PYTHON(./temp/function.py "correct" "replacement" "crust" "abracadabra" "craze")
