How to use packages in Django?

Question

Django

Explain to a newbie how to use a package/module/app in your django project. I can not understand. I am using PyCharm. For example, let's take a plugin in cms wordpress: you downloaded it, uploaded it, clicked install, and a new function was displayed on your site (gallery, slider, similar entries in the slidebar). So far I've gotten to the point where I downloaded the package from djangopackages.org, what's next? Where to put him? How to work with it, customize it for my project.

Answer 1

$ virtualenv virtenvname -p /usr/bin/python3
$ pip install package
$ vim file.py
import package

See Python books for details.
