Advanced Python Programming / Next-Level Python (TTPS4850)

Course Objectives

This course is approximately 50% hands-on, combining expert lecture, real-world demonstrations and group discussions with machine-based practical labs and exercises.  Our engaging instructors and mentors are highly experienced practitioners who bring years of current "on-the-job" experience into every classroom.  

Working in a hands-on learning environment led by our expert practitioner, attendees will learn advanced skills needed to:

• Leverage OS services
• Add enhancements to classes
• Code graphical interfaces for applications
• Understand advanced Python metaprogramming concepts
• Create easy-to-use and easy-to-maintain modules and packages
• Implement and run unit tests
• Create multithreaded and multi-process applications
• Interact with network services
• Design professional scripts
• Query databases
• Process XML, CSV,  and JSON data
• Working with more data types if time permits
• Using type hints if time permits

Need different skills or topics?  If your team requires different topics or tools, additional skills or custom approach, this course may be further adjusted to accommodate.  We offer additional python, web development, data science, machine learning and other related topics that may be blended with this course for a track that best suits your needs. Our team will collaborate with you to understand your needs and will target the course to focus on your specific learning objectives and goals.

Course Prerequisites

This in an intermediate and beyond level Python course geared for students experienced with Python who want to use Python in web development projects or automate or simplify common tasks with the use of Python scripts.  Basic incoming practical experience working with Python is required, along with a working, user-level knowledge of Unix/Linux, Mac, or Windows.  This course does not cover Python fundamentals.
