Python Flask: Make Web Apps with Python

Create and run a Flask web app in a virtual environment, define routes like /hello and the default /, return text from functions, and start the server on port 5000.

Create and map routes to functions in a Flask app, including slash, index, author, and copyright routes, install Flask in a virtual environment, then run and test the server.

Explore dynamic routes in Flask, using optional parameters to create flexible urls and map them to functions, while also understanding static routes and parameter handling.

Learn to build web apps with Flask templates, from creating a virtual environment and installing Flask to rendering templates with render_template and mapping routes to index pages.

Explore template variables in Python Flask to create dynamic routes, pass a name parameter to render_template, and render personalized content in templates.

Create a context dictionary of variables and pass it to the rendered template function. Iterate the dictionary with items() in Python 3 and render a table of key-value pairs.

Master control flow in templates with if statements and loops. Pass lists to templates and render content conditionally for dynamic pages like a shopping cart.

Build a Flask web app and apply css by linking a style sheet in templates. Set up virtual environments, static and templates directories, render templates, and style the hello page.

Set up a virtual environment and install flask to build a bmi calculator with height and mass inputs, posting to /BMI, converting inputs, calculating bmi, and displaying results with bootstrap.

Learn how Flask handles http get and post requests using templates and forms to collect user input, post login data, and navigate to a success page.

Create a Flask file upload workflow with two routes, an upload form, and a post handler, saving uploaded files to the project directory and confirming success.

Learn how cookies, simple text files stored on a user's computer, enable a Flask web app to save and read a login cookie through a form and post requests.

Learn to replace cookies with server-side sessions in Flask, storing user data as key-value pairs and persisting until deleted. Set a secret key, access session['username'], and clear session on logout.

Learn how to use SQLite in a Flask web app by creating a file-based database, defining a users table, inserting and retrieving data, and rendering it in templates.

Use Flask with SQLAlchemy to map Python classes, like customer, to database tables, avoiding data duplication. Define models, create the database, and access data by objects through routes.
