Then i installed python 3.5 version and still got the same error.
now i am trying to install the older version of Cherrypy and downloaded the 
file in my downloads folder and then instead of "PIP" i used:
*python setup.py *command in my Lx terminal but i am getting these errors:


pi@raspberrypi:~/Downloads/cherrypy-16.0.0 $ python setup.py

Make sure you're either building from a fully intact git repository or PyPI 
tarballs. Most other sources (such as GitHub's tarballs, a git checkout 
without the .git folder) don't contain the necessary metadata and will not 
work.

For example, if you're using pip, instead of 
https://github.com/user/proj/archive/master.zip use 
git+https://github.com/user/proj.git#egg=proj

i am totally new to raspbian and Panstamp and facing these errors.
please forgive me if i am doing silly mistakes ,thanks in advance.

i did install new version of python and uninstalled the older version but 
still i see python 2.7 everywhere in my above errors. dont know why
