Python isn't being assaulted on any front. We have always had multiple programming languages and some are better than others.
My issue is that we seem to have these fad languages, like Ruby-on-rails. I still remember when it was rammed down our throats on HN around ~2008 and you were instantly down voted if you wanted to objectively talk about it's pros and cons.
Now, all of the same people from that community (which I noticed, are mostly designers, not developers) have jumped ship and moved into Javascript frameworks like Ember.js and node.js.
PHP, while flawed and not cool anymore, is still one of the most popular languages.
Python will be around for a long time.
