πŸ“š Quick Study Guide

  • 🌐 Flask Routing: Defines how an application's endpoints (URLs) respond to client requests.
  • βš™οΈ `@app.route()`: A decorator in Flask used to bind a function to a specific URL. For example: `@app.route('/')` will route the root URL to the decorated function.
  • πŸ”— URL Building: Use `url_for()` to dynamically generate URLs based on the function name. This helps maintain routes if URLs change.
  • πŸ“„ HTML Templates: Use Jinja2 templating engine to create dynamic HTML pages in Flask.
  • πŸ“¦ Template Rendering: Flask uses `render_template()` to render HTML templates and pass data to them. For example: `render_template('index.html', name=user_name)`
  • πŸ—‚οΈ Template Folder: By default, Flask looks for templates in a folder named `templates` located in the same directory as the main application file.
  • πŸ”‘ Jinja2 Syntax: Jinja2 uses `{{ ... }}` for expressions (e.g., displaying variables), `{% ... %}` for statements (e.g., loops and conditionals), and `{# ... #}` for comments.
