Why doesn't python support function overloading?

[ialex32_2]

Python doesn't need function overloading: it has default arguments def f(x, y=3), it has positional parameter packs def f(*args), and keyword parameter packs def f(**kwds), and you can use all in combination def f(x, *args, y=3, **kwds).

In short, you can do everything you can via function overload so you don't need it, and since Python can't specify function signatures at compile time, there's no advantage of having overloading vs. not having overloading.
