What is Flask routing and how does it work?

Flask routing is the mechanism that maps URLs to functions in a Flask application. It allows you to define what content is displayed for different URLs.

Can you show me a simple example of Flask routing?

Sure! Here's a basic example:

from flask import Flask

app = Flask(__name__)

@app.route('/')
def home():
    return 'Welcome to the Home Page!'

@app.route('/about')
def about():
    return 'This is the About Page!'

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

What does the @app.route decorator do?

The @app.route decorator is used to bind a function to a specific URL. It tells Flask to execute that function when the URL is accessed.

Can I have multiple routes for the same function?

Yes, you can specify multiple routes for the same function by passing a list to the @app.route decorator, like this:

@app.route('/home')
@app.route('/')
def home():
    return 'Welcome to the Home Page!'
