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. 
assistant:
Let's start by running some experiments on the function to understand its behavior.

COMMAND: PYTHON(./temp/function.py "hello" "world" "2021" "python" "function")
user:
Response: Function input - output pairs: (hello, Hello) (world, World) (2021, 2021) (python, Python) (function, Function) 

assistant:
It seems like the function is capitalizing the first letter of each input string. Let's test some more inputs.

COMMAND: PYTHON(./temp/function.py "apple" "banana" "123" "mixedInput1" "mixedInput2")
user:
Response: Function input - output pairs: (apple, Apple) (banana, Banana) (123, 123) (mixedInput1, Mixedinput1) (mixedInput2, Mixedinput2) 

assistant:
Based on these tests, I can describe the function and provide a code approximation.

[DESCRIPTION]: The function capitalizes the first letter of each input string and leaves the rest of the characters unchanged. If the first character is not a letter, it remains unchanged.

[CODE]: 
```python
def f(x: str) -> str:
    return x.capitalize()
``` 

Feel free to test more inputs if you'd like, or let me know if you need any further help.
