I have a great way to learn python AI for free!
There is also a paid option for a micro-masters certificate from Columbia (which is accepted for credit towards a master in some colleges). However, if you intend to complete all of them during the set period be prepared to work from 32–40 hours a week. If not, just learn at your own pace for free…
Micro-masters in Artificial Intelligence classes, hosted by Columbia in edX:
(If you are mostly into AI in software without graphics, the best would be 1 and 2)
What do you need to know before you take them?
Remember these are graduate level AI classes, but do not require previous AI experience. Nevertheless, they do require some math (you can’t do AI without this level of math) and programming experience (which I assume you have, based on your question):
The classes officially begin in September 11 (but you can enroll at any time, or after it ends, but without a certificate), good luck!
