Compare CherryPy and Pyramid

CherryPy allows developers to build web applications in much the same way they would build any other object-oriented Python program. CherryPy has built-in tools for sessions, static files, cookies, file uploads, caching, encoding, authorization, compression, and many more.

Pyramid is a web framework that is written in Python and is based on WSGI. It is minimalistic and inspired by Zope, Pylons, and Django. Before 2010, Pyramid was known as repoze.bfg.

Let's see how CherryPy and Pyramid compare on various factors and features and which to choose when.
