News website using flask and newsapi - Setup Environment : Part 2

Hello guys,
For every project our first step is to setup the environment.

1] Install Python
Obviously we are using flask which is python framework so we need to install python.
How to install python?
If you are a beginner, watch my previous series  21 days python

2]Setting up a virtual Envrionment
We have to create a virtual environment
The venv the module provides support for creating lightweight “virtual environments” with their own site directories, optionally isolated from system site directories. Each virtual environment has its own Python binary (which matches the version of the binary that was used to create this environment) and can have its own independent set of installed Python packages in its site directories.
Basically, Virtual is a separate place from you system environment.
Packages in the system will not be included in virtual environment.

Install flask

pip install virtualenv

Create directory newsapp

mkdir newsapp

Change directory and move on to newsapp 

cd newsapp

start virtual environment

virtualenv env

You can change the name of environment replace env with myenv or any other

Now we have to start a virtual environment

\env\Scripts\activate.bat

This will show output like this (env) mean actiavte

(env) E:\flask\newsapp>

3] Setting up Flask

Now install flask 

pip install Flask

This may take some time

To Check use 

flask --version

This will show

Python 3.7.6

Flask 1.1.2

Werkzeug 1.0.1
