Flask helps build web applications and handle HTTP requests in Python.
Create a new virtual environment in your project folder and
pip3 install flask.
In your project, make a new file called
app.py and add this:
from flask import Flask # Instantiate the application based on this file app = Flask(__name__) # Decorator used to handle HTTP requests (GET by default) # When a user goes to the root of the web page, @app.route("/") # Execute the following function def hello_world(): # Return the following webpage to the user return "<p>Hello, World!</p>"
In the project folder, you should now be able to
flask run, which will create a development server at localhost. Go to the listed address and check if your Hellow World app is up.
