PIP

PIP is a package management program that let you install or upgrade various packages written in Python. In terms of operation(usage), it works very similary to Linux software management tool like apt-get or yum. So if you have a little bit of experience of Linux, PIP operation would already look familiar with you. If you don't have any experience with Linux, don't worry. PIP is very simple and handy command line program that comes with Python installation by default.

PIP is being updated indepently from Python framework. So the pip in your current Python installation package may not be the latest version of PIP.

You can upgrade pip itself using python as shown below.
