Can function overloading be used in Python?

In Python, function overloading as seen in languages like Java or C++ doesn't exist. However, you can achieve similar behavior using default arguments or variable-length arguments.

What are default arguments and how do they work?

Default arguments allow you to define a function with default values for certain parameters. If the caller doesn't provide a value for those parameters, the default value is used.

Can you give me an example of using default arguments?

Sure! Here's a simple example:

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

In this case, if you call greet('Alice'), it will return 'Hello, Alice!'. If you call greet('Alice', 'Hi'), it will return 'Hi, Alice!'.

What about variable-length arguments?

Variable-length arguments allow you to pass a variable number of arguments to a function. You can use *args for non-keyword arguments and **kwargs for keyword arguments.
