Can you explain what using **kwargs in Python means and how it works?

In Python, **kwargs is used in a function definition to collect all named arguments that were not explicitly listed in the parameter list into a dictionary. This allows the function to accept an arbitrary number of named arguments.

For example:

def example_func(**kwargs):
    for key, value in kwargs.items():
        print(f"{key} = {value}")

example_func(name="Ivan", age=30)

The output will be:

name = Ivan
age = 30

Thus, **kwargs is useful when it is not known in advance which specific named parameters will be passed to the function.
