How to use virtual environment in Python

Question

I am working on a project offered from my college and I am doing some project of mines in my current machine. How can I create a virtual environment so that I keep my packages seperated?

Answer 1

Virtual environment is very common with Python developers. Now as you are planning to use virtual environment then you should know that you must install python then pip then virtual environment.

You can follow this document here:

http://docs.python-guide.org/en/latest/dev/virtualenvs/

You can also use pyenv it is easy to install and serves the purpose.

Hope this helps.

Answer 2

venv (for Python 3) and virtualenv (for Python 2) allow you to manage separate package installations for different projects. They essentially allow you to create a “virtual” isolated Python installation and install packages into that virtual installation. When you switch projects, you can simply create a new virtual environment and not have to worry about breaking the packages installed in the other environments. It is always recommended to use a virtual environment while developing Python applications.

To create a virtual environment, go to your project’s directory and run venv. If you are using Python 2, replace venv with virtualenv in the below commands.

On macOS and Linux:

python3 -m venv env

On Windows:

py -m venv env

The second argument is the location to create the virtual environment. Generally, you can just create this in your project and call it env.

venv will create a virtual Python installation in the env folder.

Hope this will help
