What is the difference between default arguments and variable length arguments?

Can you explain the difference between default arguments and variable length arguments in Python?

Sure! Default arguments are predefined values for function parameters, while variable length arguments allow you to pass a variable number of arguments.

Can you give me an example of default arguments?

Of course! Here's a simple example:

def greet(name='Guest'):
    return f'Hello, {name}!'

In this case, if you call greet() without an argument, it will use 'Guest' as the default.

And what about variable length arguments?

Variable length arguments are defined using *args and **kwargs. For example:

def add_numbers(*args):
    return sum(args)

This function can take any number of arguments.

Thanks! So, can I use both in the same function?

Yes, you can! Just remember that default arguments should come before variable length arguments in the function definition.
