Target Audience

All students should be able to comfortably write Python scripts using basic data types, program structures, and the standard Python library. Teams starting a new service should also consider Build REST APIs with Python and FastAPI.

Description

The Build REST APIs with Python and Flask and RestX course is designed for computer programming professionals seeking to understand the benefits and principles of a REST API. Participants will review the HTTP protocol and its application to REST APIs, and explore how to connect to a Postgresql or SQL Server database with Python and SQLAlchemy. The curriculum includes a review of Python Web Framework options and an overview of tools commonly used in REST API development. Learners will gain hands-on experience in building a REST API using Python, Flask, and RestX REST API framework. The course concludes with a review of options for deploying a REST API to the cloud, equipping learners with the skills to develop and deploy robust REST APIs.
