How do I implement function overloading 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.

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

Sure! Here's a simple example:

def add(a, b=0):
    return a + b

In this case, if you call add(5), it will return 5, and if you call add(5, 3), it will return 8.

What about using variable-length arguments?

You can use *args to accept a variable number of arguments. For example:

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

This allows you to call add(1, 2) or add(1, 2, 3, 4) and get the sum.

Are there any libraries that support function overloading?

Yes, you can use libraries like NumPy or functools which provide decorators like @singledispatch to achieve function overloading based on the type of the first argument.
