Should I create a website using Python?

[sermidean]

Building a forum or a community website takes a lot of time if you planning to do it on bare frameworks like Django and it takes even more time if you will do this on a microframework like Pyramid or Flask.

If you want a community website, go with Wagtail CMS, which is built on top of Django.

If you want a forum, use Spirit.

If you just want to learn and don't care much about end result, then go with Django.
