Installing and using the virtual environment

Now we will see how to install the virtual environment and how to activate it. 

To install the virtual environment on Linux, perform the following steps:

1. First check whether pip is installed or not. We are going to install pip for python3: 

sudo apt install python3-pip

2. Install the virtual environment using pip3:

sudo pip3 install virtualenv

3. Now we will create the virtual environment. You can give it any name; I have called it pythonenv:

virtualenv pythonenv

4. Activate your virtual environment:

source venv/bin/activate

5. After your work is done, you can deactivate virtualenv by using following command:

deactivate

In Windows, run the pip install virtualenv command to install the virtual environment. The steps for installing virtualenv are same as with Linux.
