The Python Web App Development with Flask Literacy (Beginner Level) benchmark evaluates your ability to use the Python Requests package to make HTTP requests and parse the responses. You will be assessed on your skills in recognizing the need for a web framework and the features of Flask that speed up the development of a web application, as well as creating a basic website with Flask using boilerplate HTML files and templates. A learner who scores high on this benchmark demonstrates that they have the skills to make HTTP requests with Python and build a simple website using Flask.
