The use of a Virtual Environment is to test python code in encapsulated environments, and to also avoid filling the base Python installation with libraries we might use for only one project.
pip install virtualenv
Install virtualenvwrapper-win (Windows)
pip install virtualenvwrapper-win
Make a Virtual Environment named
Anything we install now will be specific to this project. And available to the projects we connect to this environment.
Set Project Directory
To bind our virtualenv with our current working directory we simply enter:
To move onto something else in the command line type
deactivateto deactivate your environment.
Notice how the parenthesis disappear.
Open up the command prompt and type
workon HelloWoldto activate the environment and move into your root project folder
From Poetry website
Poetry is a tool for dependency management and packaging in Python. It allows you to declare the libraries your project depends on and it will manage (install/update) them for you.
pip install --user poetry
Create a new project
poetry new my-project
This will create a my-project directory:
my-project ├── pyproject.toml ├── README.rst ├── poetry_demo │ └── __init__.py └── tests ├── __init__.py └── test_poetry_demo.py
The pyproject.toml file will orchestrate your project and its dependencies:
[tool.poetry] name = "my-project" version = "0.1.0" description = "" authors = ["your name <email@example.com>"] [tool.poetry.dependencies] python = "*" [tool.poetry.dev-dependencies] pytest = "^3.4"
To add dependencies to your project, you can specify them in the tool.poetry.dependencies section:
[tool.poetry.dependencies] pendulum = "^1.4"
Also, instead of modifying the pyproject.toml file by hand, you can use the add command and it will automatically find a suitable version constraint.
$ poetry add pendulum
To install the dependencies listed in the pyproject.toml:
To remove dependencies:
poetry remove pendulum

From Pipenv website
Pipenv is a tool that aims to bring the best of all packaging worlds (bundler, composer, npm, cargo, yarn, etc.) to the Python world. Windows is a first-class citizen, in our world.
pip install pipenv
Enter your Project directory and install the Packages for your project
cd my_project pipenv install <package>
Pipenv will install your package and create a Pipfile for you in your project’s directory. The Pipfile is used to track which dependencies your project needs in case you need to re-install them.
pipenv uninstall <package>
Activate the Virtual Environment associated with your Python project
Exit the Virtual Environment

Anaconda is another popular tool to manage python packages.
Where packages, notebooks, projects and environments are shared. Your place for free public conda package hosting.
Make a Virtual Environment
conda create -n HelloWorld
To use the Virtual Environment, activate it by:
conda activate HelloWorld
Anything installed now will be specific to the project HelloWorld
Exit the Virtual Environment
