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 get started by calling the function on a few different string inputs.

COMMAND: PYTHON(./temp/function.py "hello" "world" "test" "123" "aBcDe")
user:
Response: Function input - output pairs: (hello, he2llo) (world, wo2rld) (test, te2st) (123, 1223) (aBcDe, ab2cde) 

assistant:
It seems the function is adding a "2" in between the first and second characters of the input string and returns the entire string in lowercase. Let's test a few more examples to verify this.

COMMAND: PYTHON(./temp/function.py "Computer" "Strings" "Function" "Assistant")
user:
Response: Function input - output pairs: (Computer, comp2uter) (Strings, str2ings) (Function, func2tion) (Assistant, assi2stant) 

assistant:
Based on the given input-output pairs, the function appears to be adding a "2" in between the first and second characters of the input string and returns the entire string in lowercase.

[DESCRIPTION]: The function adds a "2" between the first and second characters of the input string, and converts the entire string to lowercase.

[CODE]:
def approximate_function(input_string):
    return input_string[0].lower() + '2' + input_string[1:].lower()
