Python and TCL: Tips and Tricks for Nuke
A good place to learn and practice Python
Codeacademy is similar to Codewars in that it has an in browser interactive IDE for writing your code, and it tests your code to see if you passed the challenge, but the challenges are much more structured. Each challenge builds on the previous one. I haven't use Codeacademy as much as Codewars because by the time I tried it it was a bit basic, and I liked being able to see other peoples solutions in Codewars, but it would be a great place to start.
A great site for practicing your coding skills
Codewars has many user created challenges called Kata. These challenges are matched to your skill level, and after you have completed them you can see other people's solutions to the same challenge, which is a great way of learning.

Dan Ebberts is an After Effects expressions genius.
I found Dan answering posts over at creativecow.net. This site has loads of example After Effects expressions. In most cases you can take the maths that he uses and rebuild the expressions in other apps.

Python for Nuke 101
Ben McEwan's introduction course on writing Python code for Nuke
The first big help was Python for Nuke 101 by Ben McEwan. This is a great introduction course. Ben covers all the python basics that you need to know, but, unlike a lot of the beginners python courses, he is instantly approaching it from a VFX point of view. The classes a detailed, but easy to follow. The examples are useful and relevant. He provides great documentation to go along with the videos and the challenges that he sets after each course push you just enough, without being so hard you feel hopeless.
