How to get CherryPy version

python -c "import cherrypy;print cherrypy.__version__"

In ubuntu, you just need to check the package version:

apt-cache policy python-cherrypy3

For example, in my system:

python-cherrypy3:
  Installed: 3.1.2-1
  Candidate: 3.1.2-1
  Version table:
 *** 3.1.2-1 0
        500 http://archive.ubuntu.com/ubuntu/ oneiric/universe amd64 Packages
        100 /var/lib/dpkg/status

Python 3 syntax:

python -c "import cherrypy;print(cherrypy.__version__)"
