This course has a 50% hands-on labs to 50% lecture ratio with engaging instruction, demos, group discussions, labs, and project work.

This course is about 50% hands-on lab and 50% lecture, with extensive programming exercises designed to reinforce advanced Python programming skills, concepts and best practices learned in the lessons. Students will write numerous Python scripts to reinforce the major concepts covered in this course. The courses will increase in complexity as more sophisticated techniques are introduced. At the end of each lesson, students will be tested witha set of review questions to ensure that he/she fully grasps the topic. Our courses include ample materials and labs to ensure all students are either appropriately challenged, or assisted, at all times-no matter their skill level.

Before attending this course, you should have:

• Experience writing Python scripts
• Working knowledge of Unix/Linux, Mac, or Windows

This is not a basic course.

Experienced Developers, Engineers, Administrators, and anyone focused on advanced skills for enterprise development.
