Flask
Flask is a lightweight web framework written in Python. It's designed to be simple, flexible, and easy to get started with, making it ideal for beginners and professionals alike. Flask doesn't enforce dependencies or project layout, which means you have the freedom to build your application however you want.
Key Features
- Minimalist: Comes with the bare essentials. Add only what you need.
- Flexible: Doesn't impose a specific project structure.
- Built-in Development Server: Helps you test your application locally.
- Routing Support: Easily map URLs to Python functions.
- Jinja2 Templating: Powerful templating engine for rendering dynamic HTML.
- Extensible: Add features through Flask extensions (e.g., Flask-Login, Flask-WTF).
Basic Example
from flask import Flask
app = Flask(__name__)
@app.route("/")
def home():
return "Hello, Flask!"
if __name__ == "__main__":
app.run(debug=True)
