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 running some experiments on the function. 

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

assistant:
It seems like the function is returning the same input string. Let's try a few more tests with different inputs.

COMMAND: PYTHON(./temp/function.py "example" "!@#$%" "   " "<>+-*/&" "Lorem Ipsum")
user:
Response: Function input - output pairs: (example, example) (!@#$%, !@#$%) (   ,    ) (<>+-*/&, <>+-*/&) (Lorem Ipsum, Lorem Ipskm) 

assistant:
It appears that the function mostly returns the same input string, with some exceptions (in this case, "Lorem Ipsum" became "Lorem Ipskm"). Let's test it a bit more with longer strings and different characters.

COMMAND: PYTHON(./temp/function.py "The quick brown fox" "jumps over the lazy" "d0g and grabs the b0ne" "A1b2C3d4E5f6G7H" "Mix of *symbols* and text!")
user:
Response: Function input - output pairs: (The quick brown fox, The qkick brown fox) (jumps over the lazy, jkmps over the lazy) (d0g and grabs the b0ne, d0g and grabs the b0ne) (A1b2C3d4E5f6G7H, A1b2C3d4E5f6G7H) (Mix of *symbols* and text!, Mix of *symbols* and text!) 

assistant:
Based on the tests, the function mostly returns the input string unchanged, but sometimes changes certain characters (like "u" to "k" in "The quick brown fox" and "u" to "k" in "jumps over the lazy").

[DESCRIPTION]: The function returns the input string with occasional character substitutions.

[CODE]: 
```python
def approximate_function(input_string):
    # Based on the observed behavior, the code below is an approximation and might not cover all cases.
    change_dict = {'u': 'k', 'm': 'k'}
    
    output_string = ''.join([change_dict.get(char, char) for char in input_string])
    
    return output_string
```

Let's test the approximation function.

COMMAND: PYTHON(./temp/function.py "The quick brown fox" "jumps over the lazy" "d0g and grabs the b0ne" "A1b2C3d4E5f6G7H" "Mix of *symbols* and text!")
