How do variadic functions work in Python?

Can you explain how variadic functions work in Python?

Sure! Variadic functions in Python can accept a variable number of arguments. You can use *args for non-keyword arguments and **kwargs for keyword arguments.

Can you give me an example of a variadic function?

Absolutely! Here's a simple example:

def my_function(*args):
    for arg in args:
        print(arg)

my_function(1, 2, 3)

This function will print each argument passed to it.

What about keyword arguments? How do they work?

For keyword arguments, you can use **kwargs. Here's an example:

def my_function(**kwargs):
    for key, value in kwargs.items():
        print(f'{key}: {value}')

my_function(name='Alice', age=30)

This will print the keys and values of the passed keyword arguments.

Are there any limitations to using variadic functions?

Yes, while variadic functions are flexible, they can make code harder to read and debug if overused. It's best to use them judiciously.
