Join ILM’s Geordie Martinez in this 8 week journey inside Python.

Every week you will get access to 3+ hours of video content as well as example scripts, cheat sheets and UIs built in Designer for use in Maya’s PySide. The instructor is there to answer questions and share with you his experience as well as give feedback on your work.

You will learn proven production programming techniques and how to effectively and properly code using Object Oriented Programming and GUI programming using Pyside/Pyqt. If you are already familiar with Python, expect to solidify your skills and take them to the next level.

What you will gain from this workshop:

Knowledge of production skills
Proficiency in Python fundamentals that are applicable outside of Maya
Mastery of GUI programming
Direct and personal feedback on your work
Knowledge of Object Oriented Programming

Python is everywhere.
If you learn the basics here you can take them with you to other industries like web site development, game development, statistics and data analysis, science animation, etc.
In this course you’ll learn Python fundamentals that can be used in any python setting but also specifically using it inside Maya and PyQt/Pyside.
