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 test the function with different inputs to understand its behavior:

COMMAND: PYTHON(./temp/function.py "hello" "world" "12345" "test" "abcdef")
user:
Response: Function input - output pairs: (hello, hello) (world, world) (12345, 12345) (test, test) (abcdef, aQcdef) 

assistant:
Interesting. Let's test more inputs to see if we can identify any pattern:

COMMAND: PYTHON(./temp/function.py "Hello" "Python" "Sample" "function" "zyxwv" "GHIJKLMNOP")
user:
Response: Function input - output pairs: (Hello, Hello) (Python, Python) (Sample, Sample) (function, function) (zyxwv, zyxwv) (GHIJKLMNOP, GHIJKLMNOP) 

assistant:
The function seems to keep most inputs the same, except in the initial test the letter "b" was replaced with "Q". Let's test more inputs focusing on small changes and letters around "b":

COMMAND: PYTHON(./temp/function.py "b" "B" "ab" "ac" "aQc" "ba" "bc" "cab" "bbc")
user:
Response: Function input - output pairs: (b, Q) (B, B) (ab, aQ) (ac, ac) (aQc, aQc) (ba, Qa) (bc, Qc) (cab, caQ) (bbc, QQc) 

assistant:
Based on the tests, it seems the function replaces the letter "b" with "Q". Here's the description and code that approximates the behavior of the function:

[DESCRIPTION]: The function replaces all occurrences of the lowercase letter "b" with the uppercase letter "Q" in the input string.

[CODE]:
```python
def approximate_function(input_string):
    return input_string.replace("b", "Q")
```
