How to create a Virtual Environment in Python

Why do you need to create a Virtual Environment?

Sometimes, we need to have some dependencies of your project to be isolated

from dependencies present in the system site to avoid conflicts and Virtual 

Environment lets you do this.

Creating a virtual environment lets you have your own independent set of 

installed Python packages in your site directories which is apart from system

site directories. Virtual Environment lets you create an isolated environment 

for your python projects.

Creating a Virtual Environment :

Step 1: Install Virtual Environment package:

pip install virtualenv

Step 2: Create a new directory to work with and head over there:

mkdir venv

cd venv

Step 3: Now, create a new Virtual Environment in this directory

virtualenv myvenv

This creates a new virtual environment with the name "myvenv".

For using this Environment's packages you need to activate it.

Step 4: Activate the environment 

myvenv\Scripts\activate

Now you are in virtual environment and ready to go with it.

Step 5: Deactivate the virtual environment

deactivate
