Introduction

This workshop is geared towards students with little to no scripting/programming experience. By the end of this workshop, you will have the knowledge to write and run Python scripts inside and outside of Maya. You will not learn everything about Python from this workshop. This workshop includes all the basic information you should know in order to be proficient in reading, writing, running, and modifying Python scripts. The purpose of this workshop is not to make you expert Python scripters, but to give you a solid foundation from which in further your Python studies.

Conclusion

After reading these notes, you should have a good understanding of how to write and run Python scripts inside and outside of Maya. There is still plenty to learn though. There are hundreds of Maya commands and plenty of useful modules out there to experiment with. I recommend continuing your Python education by looking through the references included with these notes, reading other peoples’ scripts, and experimenting with your own scripts. Good luck!
