Python Flask 2023

Python Flask is a micro web framework for Python. It is used to build web applications quickly and with minimal code. In this lesson, we will introduce you to the basics of Flask and how to get started with it.

What is Flask?

Flask is a lightweight and modular framework that provides tools and libraries for building web applications in Python. It is easy to learn and has a simple and elegant syntax, making it a popular choice for developers.

Getting Started with Flask

To start using Flask, you need to have Python installed on your computer. Once you have Python installed, you can install Flask using the following command:

pip install Flask

After installing Flask, you can start building your web applications using the Flask framework. You can create a new Flask application using the following code:

from flask import Flask
app = Flask(__name__)

@app.route('/')
def index():
return 'Hello, World!'

if __name__ == '__main__':
app.run()

This code creates a simple web application that displays “Hello, World!” when you open the root URL of the application.
