Nope, with Python, unless you're using Django, most of your stuff is done with Python - there are frameworks like Flask but they provide a minimal set of tools to work with web concepts like routing and sessions. CPU won't be the bottleneck until storage is as fast as CPUs. SSDs close the gap a tiny bit, but nowhere near enough.
