Day 22 of #100DaysOfCode in Python: Taking the First Step with Flask

1. Flask: An Introduction

Flask is a lightweight, “micro” web framework written in Python. It’s designed to make getting started with web development quick and easy, without the overhead of learning a full-stack framework. With Flask, you can develop web applications, from simple single-page sites to more complex database-driven ones.

2. Why Choose Flask?

• Simplicity and Flexibility: Flask gives developers the flexibility to structure their projects as they like, without enforcing any particular project or code layout.
• Extensions: Flask can be easily extended with modules to add functionalities like database integration, form validation, authentication, and more.

from flask import Flask

app = Flask(__name__)

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

if __name__ == "__main__"…
