In this video tutorial, we will be showing you how to get started with Flask and build a web application. Flask is a python microenvironment designed to be lightweight and offers you the freedom to create web applications without limitations on the modules and packages you want to use and the methods and structure you want to follow.

Commands used: 
pip 3 install virtual env
virtualenv --python=python3 python-tutorial
source bin/activate
pip install flask
touch flask-tut.py
vim flask-tut.py

Add the following code to the file flask-tut.py:

# Import the Flask package
from flask import Flask

# Initialize Flask
app = Flask(__name__)

# Define the index route
@app.route("/")
def index():
return "Hello from Flask!"

# Run Flask if the __name__ variable is equal to __main__
if __name__ == "__main__":
app.run()

Now execute the file by running:

python3 flask-tut.py
