The usual term for this is "polymorphism".

I assume you mean Vector in the last line.

I find this the easiest way to handle this situation:

class Vector(object, *args):
    if len(args) == 1:
        # Assume the caller passed a list argument.
        args = args[0]
    x, y, z = args  # Unpack the arguments.
    # then process as normal.
