It gives developers flexibility and is a more accessible framework for new developers since you can build a web application quickly using only a single Python file. The index() view function returns the result of calling render_template() with index.html as an argument, this tells render_template() to look for a file called index.html in the templates folder. Both the folder and the Advanced Python Web Dev Using Flask Lessons file do not yet exist, you will get an error if you were to run the application at this point. You’ll run it nonetheless so you’re familiar with this commonly encountered exception. The course includes a complete Python refresher that starts with the very basics and quickly takes you through the advanced features, including functions, decorators, and object-oriented programming.

• In Easy Language, It combines a template (the layout of the page) with data (the specific information you want to show) to create a dynamic web page.

This section covers Django starting right from basics, to the point that you build a sample mini web app using Django. Then you get to learn about Flask which is also a web development framework. Flask is an API of Python that allows us to build up web-applications. Flask’s framework is more explicit than Django’s framework and is also easier to learn because it has less base code to implement a simple web-Application. A Web-Application Framework or Web Framework is the collection of modules and libraries that helps the developer to write applications without writing the low-level codes such as protocols, thread management, etc. Flask is based on WSGI(Web Server Gateway Interface) toolkit and Jinja2 template engine.

This is a Flask web application.

This role may require knowledge of additional frameworks which can be acquired through a Flask boot camp, as well as specific educational milestones such as a bachelor’s degree or a master’s degree.
