But, think of your python project being complex, such as making a request to get photos, calculating your income or saving data into the database. These are different things, and you can’t focus on getting everything written down as you might be busy in trying to get awesome cool new feature out the door. So, why not use the tools and libraries other amazing software engineers have already made for you? That is where virtual environment comes in.

For each project, you can have a virtual environment where only the libraries of that project will be part of the project.

It is really simple to actually create a virtual environment

Create a virtual environment

python -m venv virtualenv

Use that virtual environment on Mac & Linux, bash

$ source virtualenv/bin/activate # for bash, linux, mac

And for windows

D:\dev> virtualenv\Scripts\activate.bat

Verify that virtual environment is activated

To verify that the virtualenv is activated, you will see something like this

(venv) D:\dev>
