What is the order of parameters in Python functions?

Can you explain the order of parameters in Python functions?

Sure! In Python, the order of parameters in a function definition is: positional parameters, then default parameters, followed by *args, **kwargs, and finally keyword-only parameters.

What are *args and **kwargs used for?

*args allows you to pass a variable number of positional arguments to a function, while **kwargs allows you to pass a variable number of keyword arguments.

Can you give me an example of a function using *args and **kwargs?

Of course! Here's an example:

def example_function(*args, **kwargs):
    print('Positional arguments:', args)
    print('Keyword arguments:', kwargs)

You can call it like this: example_function(1, 2, a=3, b=4).

What happens if I mix positional and keyword arguments?

If you mix them, positional arguments must come before keyword arguments in the function call. For example, example_function(1, 2, a=3) is valid, but example_function(a=3, 1, 2) will raise a SyntaxError.
