&gt;&gt; why has Python 3 adoption been so slow<p>Really this topic is coming to an end. Most libraries support Python 3 and if they don&#x27;t there&#x27;s better alternatives.<p>For new users and new projects there&#x27;s no reason now except personal preference to choose Python 2 and in fact beginners who start with Python 2 are just instantly incurring a learning debt upon themselves to be paid down the track when they have to move to Python 3.<p>The community has some extremely vocal Python2 diehards but their arguments no longer hold water.<p>&gt;&gt;why has Python 3 adoption been so slow?
Whatever, it&#x27;s just history now.
