How does function overloading work in Python?

Can you explain how function overloading works in Python?

In Python, function overloading is not supported directly like in some other languages. However, you can achieve similar behavior using default arguments or variable-length arguments.

What are default arguments and how do they help with overloading?

Default arguments allow you to define a function with optional parameters. If the user doesn't provide a value, the default is used, enabling different behaviors.

Can you give me an example of using default arguments for overloading?

Sure! Here's a simple example:

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

You can call greet('Alice') or greet('Alice', 'Hi').

What about variable-length arguments?

Variable-length arguments allow you to pass a variable number of arguments to a function using *args and **kwargs. This can also simulate overloading.
