What methods can be used to pass parameters to functions and which ones do you know?

In Python, function parameters can be passed in several ways:

1. Positional parameters — passed in the order they are declared.
2. Named parameters (keyword arguments) — passed with the parameter name, order does not matter.
3. Default parameters — parameters with default values, used if no argument is provided.
4. *Variable-length arguments (args) — allow passing an arbitrary number of positional arguments.
5. **Variable-length named arguments (kwargs) — allow passing an arbitrary number of named arguments.

Example:

def example(a, b=2, *args, **kwargs):
    print(f'a={a}, b={b}')
    print(f'args={args}')
    print(f'kwargs={kwargs}')

example(1, 3, 4, 5, x=10, y=20)

Output:

a=1, b=3
args=(4, 5)
kwargs={'x': 10, 'y': 20}
