How do I implement routing in Flask?

In Flask, you can implement routing using the @app.route() decorator. This allows you to define the URL paths for your application.

Can you show me a simple example?

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(debug=True)

What if I want to pass parameters in the URL?

You can pass parameters by including them in the route. For example:

@app.route('/user/<username>')
def show_user_profile(username):
    return f'User: {username}'
