A typical Flask application begins by importing the Flask class from its module and initializing it. Here’s an example of how you might set up your first Flask app:
from flask import Flask
app = Flask(name) # Initializing the Flask application.
Once initialized, you can define routes using `@app.route()`. For instance, here’s a basic route that returns a greeting message:
@app.route('/')
def home():
return "Welcome to my Flask app!"
Flask also allows for template-based rendering through Jinja2. Here’s how you might structure your templates within the Flask framework:
templates = {
'index.html': '''
<!DOCTYPE html>
<html>
<head><title>My Flask App</title></head>
<body>
<h1>Welcome to my Flask app!</h1>
</body>
</html>
''',
}
Comparatively, Django offers a more comprehensive framework by integrating with databases and providing out-of-the-box authentication systems. However, this simplicity makes Flask a preferred choice for smaller projects or those requiring minimal setup.
