Welcome, you have found a very good programming language. I'm glad you
like it.

This is good. Python 3 makes it much easier to do the right thing with
writing systems worldwide.

Because Python 2 has a lot of inertia. There is a great amount of
existing Python 2 code, and many other systems built on that code.
Change takes time.

Be glad that you are learning Python 3 now! There has been great
improvement in the Python 3 landscape in recent years.

You have that backward; the website reflects the current needs of the
community. While the PYthon 3 transition is still going through rapid
change, the safest choice is still Python 2 for *existing * uses.

But for newcomers like yourself, Python 3 is now the right choice and
has been for some years. Congratulations!

Yes, much has already been done, and much is still being done now. But
there is still more work to do, as you observed.

You can help by contacting the specific projects you rely on which still
do not have Python 3 support, and ask those people kindly how you can
help. We all get there faster by helping each other!
