How to Install PIP on Windows
The following instructions should work on Windows 7, Windows 8.1, and Windows 10:

pip3 , Download PyPi : https://pypi.org/project/pip/  or   https://sourceforge.net/projects/ppip/files/latest/download


Download the get-pip.py installer script: https://bootstrap.pypa.io/get-pip.py 
If you’re on Python 3.2, you’ll need this version of get-pip.py instead. Either way, right-click on the link and select Save As… and save it to any safe location, such as your Downloads folder.
Open the Command Prompt and navigate to the get-pip.py file.
Run the following command on CMD command line:
