Does Python have Multiple Inheritance ?

Wikipedia says Python has Multiple Inheritance, is this true ?

Good grief. You can use Wikipedia but you can't use Google?

see, multiple inheritance!

It seems the OP cannot even use Wikipedia. Between the links to the
page he cites
there is http://en.wikipedia.org/wiki/C3_linearization, which is the
way Multiple Inheritance is implemented in Python.

See it this way Aaron is so damb supprised that there is another language
with MI and particularly that it is Python, all order and normal action go
out the window !

Cheers,

Glad you can see the funny side.

Seriously, though, although Python does indeed support multiple inheritance,
I have the impression from comments over the years that it's used a lot less
than in other languages where it is more of a common idiom. Certainly in my
own (not negligible) use of Python, I've very rarely used it for anything
but the occasional mixin class.

I'll leave others to comment on whether this is indeed so and why
it might be

The reason is that in Python using composition is very easy, so there
is little need for MI
(which is a Good Thing).

Not to mention duck typing, which does away with the need for inheritance
altogether.

That seems a somewhat extreme point of view.

Hey, I didn't design the language, I just use it.

I'm with Steve. Multiple inheritance is still a "good" thing, especially for
mixin-classes. wxPython, for instance, wouldn't be nearly so flexible without it.

Sure. But Python doesn't _force_ you to do things that way.
