Course Details
Duration: 3 Days; Instructor-led
Introduction to Python and Django course starts by teaching students the basics of Python, then moves on to teach students how to develop Web applications using the Django framework. This class covers basics of creating basic applications using the MVC (model-view-controller) design pattern, as well as more advanced topics such as administration, session management, authentication, and automated testing.
