You're attempting to install to the system while you don't have permissions to do so. You need to either use sudo get-pip.py or get-pip.py --user.

should I use "--user" everytime I use pip for something?? since it doesnt seem to work for me unless I add --user everytime at the end of pip command

@aaashishK or learn virtualenv which allows you to create self-contained environments to install a set of python packages into, instead of needing to do so over the system environment.

pip --user is equivalent to saying "install this python package for my user account" rather than "for the whole system" so for packages you want widely available to yourself, yes that's a good idea.
