In the last few years Python has grown from being a rather obscure
scripting language developed by a man with an intense love of Eric Idle
to being the de facto standard for scripting applications in the post
production domain. This new introductory class will focus on the
fundamentals of python scripting, building up to quick, tactical tools
that can be used by vfx artists in facilities large and small to make
their lives easier and their financial masters happier.
As The Foundry's Nuke has been converted to a Python underpinning since
the release of version 5.0 a great deal of interest has developed in
existing and developing nuke artists for some understanding of the TD
magic going on under the hood. Nuke is now an incredibly scriptable
program with a very powerful set of core tools that can, in the hands
of a compositor with a good basis in Python, dramatically improve the
efficiency of many of the more redundant compositing tasks, and can
even make the bit that remains a lot more fun in the process.
This course will spend a fair bit of time getting compositors with
little or no programming / scripting knowledge up to speed; Python is
very accessible to non-programmers and as you will learn a little
Pythonic knowledge can go a very long way towards making your
compositing life a lot easier. This course syllabus will likely change
as we delve in and see how everyone does getting their feet wet. The
last two lessons, especially, will evolve in response to the type of
examples that you, the student body, would like to see and explore.

course syllabus
Class 1
The most basic Python program possible, followed by an introduction to
all of the basic variable types, including Integers, Floats, and
Strings.
Class 2
We expand on the basic numeric and string variable types presented in
Class01, and continue on to the sequential variable types, lists and
tuples. There is also some discussion of syntax and naming conventions.
Class 3
We finish introducing the basic python variable types with a discussion
of Dictionaries. We then move on to program logic flow tools such as if
/ elif / else conditionals and for loops, while loops, and list
comprehensions.
Class 4
Modules, use and abuse. Function definitions, namespaces, and variables
both global and local / private. The Try statement and exception
handling in general.
Class 5
Jumping into Nuke: basic customization through the Init.py and Menu.py
files. Folder structures and the basics of package importing. Good
installation practices, followed by How to Break Nuke in One Easy Step
... and figure out how to fix it again.
Class 6
Beyond customization. Simple one off scripts to make changes to many
nodes very fast, quick ways of finding things you thought were lost,
and the dumbest thing you'll ever see Python do to Nuke (AKA Havoc for
Fun and Profit). Some time will be spent on parsing external files to
bring arbitrary data into Nuke and use it for something.
Class 7
The Top 10 Things you should know how to script in Nuke. Including a
basic Panel GUI.
Class 8
A very brief introduction to Object Oriented Programming; this is an
advanced topic, but it can really come in helpful when you start
looking at expanding on the toolset you've already built above. Simple
Classes, an understanding of inheritance, and a foundation in the world
of OOP.
Class 9
The next two lessons will be dedicated to more advanced scripting
examples that students request, as well as a good overview of
docstrings and why they are your friend. More discussion of OOP is
likely, as is a brief introduction to the Ethics of Scripting Well.
Class 10
Continuation of the previous lesson.
