Introduction to Flask2:58
Learn how Flask turns Python code into accessible web apps across platforms. Install Flask with pip, read the docs, and build your first app together.
Creating our First Flask App5:41
Create your first Flask app by setting up main.py with static and templates folders, render an HTML page with render_template, and run a development server at localhost:5000.
Creating a Static Site9:31
Build a functional static site with Flask by creating templates and a static folder, wiring routes for home, about, services, and contact with render_template, and styling with Bootstrap.
Serving Static Files in Flask3:48
Learn how to serve static files with Flask, using a static folder for CSS, images, and downloads, render templates, and safely expose only public content.

Handling Forms in Flask9:43
Build and handle web forms in Flask by creating a simple name and email form, handling get and post requests, and saving submissions to a file.
Jinja2 Templating in Flask6:34
Flask uses Jinja2 as its default templating engine to render dynamic HTML by passing data like a marks dictionary to templates via render_template. Preview upcoming topics like inheritance and blocks.
Conditionals, Loops & Comments in Jinja27:18
Learn to use Jinja2 comments, loops, and conditionals in Flask templates to render dynamic student data, building a minimal Flask app with templates and static folders.
Template Inheritance8:43
Discover how to use template inheritance in Flask to build a base template with blocks, extend it for home, about, and contact pages, and share navbar and footer.
Changing Static Folder & Using url_for Function8:44
Learn how to use the Flask url_for function to reference static assets and templates, and customize static folders and url paths for flexible, maintainable web apps.
Query Parameters in Flask9:06
Learn to access query parameters in Flask with request.args and render them in a template. Build a minimal app with index.html showing dynamic name and token values from the URL.
