What are the best practices for using parameters in Python?

When using parameters in Python, it's important to follow best practices like using default values, keyword arguments, and type hints.

Can you explain why default values are useful?

Default values allow functions to be called with fewer arguments, making them more flexible and easier to use.

What are keyword arguments and how do they help?

Keyword arguments let you specify arguments by name, improving code readability and allowing you to skip optional parameters.

How do type hints improve parameter usage?

Type hints provide clarity on what types of arguments a function expects, helping with debugging and improving code quality.

Can you give an example of a function using these practices?

Sure! Here's a simple function:

def greet(name: str, greeting: str = 'Hello') -> str:
    return f'{greeting}, {name}!'
