Welcome to the Flask Documentation section! Here you will find comprehensive information about Flask, a micro web framework for Python. Flask is known for its simplicity and flexibility, making it a popular choice for web development.
Getting Started
Flask is a micro framework, which means it is lightweight and doesn't include all the features you might need in a web application. However, it is easy to extend with various extensions available.
Installation
To install Flask, you can use pip:
pip install Flask
Basic Structure
A basic Flask application typically consists of the following components:
app.py: The main application file.templates/: Directory for HTML templates.static/: Directory for static files like CSS, JavaScript, and images.
Key Features
Flask offers several key features:
- Routing: Define routes to map URLs to functions.
- Templates: Use Jinja2 templating engine for dynamic content.
- Extensions: Extend Flask with various plugins.
Routing
In Flask, you can define routes using the @app.route() decorator:
@app.route('/')
def index():
return 'Hello, World!'
Templates
Jinja2 is the default templating engine for Flask. You can create templates in the templates/ directory and render them with context data:
@app.route('/')
def index():
return render_template('index.html', title='Home')
