Virtual Python Environment
A Virtual Environment is a tool to keep the dependencies required by different projects in separate places, by creating virtual Python environments for them. It solves the “Project X depends on version 1.x but, Project Y needs 4.x” dilemma, and keeps your global site-packages directory clean and manageable.1

Installation
$ sudo pip install virtualenv
Create an Environment
$ which python3 or $ which python3.6
where {env-name} is the name for your project, etc. and the -p path is too the version of Python you want to use in this environment, for example Python 3.x
$ virtualenv ./venv -p /usr/bin/python3.6
Activate the VirtualEnv
$ source ./venv/bin/activate
VirtualEnv Dependencies
pip freeze
- pip freeze - pip 18.1 documentation
When you are using a virtualenv, you can specify a requirements.txt file to install all the dependencies.3
(venv)$ pip freeze > requirements.txt
(venv)$ pip install -r requirements.txt
PyCharm - virtualenv
PyCharm - virtualenv makes it possible create virtual environment using the virtualenv tool. So doing, PyCharm tightly integrates with virtualenv, and enables configuring virtual environments right in the IDE.4

Git
Git is a distributed revision control system with an emphasis on speed, data integrity, and support for distributed, non-linear workflows. Git was initially designed and developed by Linus Torvalds for Linux kernel development in 2005, and has since become the most widely adopted version control system for software development.6
