I would like to get into AI development in python but i don't know how. I really hope that i could code Artificial Intelligent by my own someday. anybody got any suggestions?
I assume you have a solid background in software engineering and mathematics. Those are fundamental for your goal. If not, the best courses on AI won't get you to where you want to be.
To get a grasp on the basics, I recommend reading the free book published on Neural Networks and Deep Learning. You might have to refresh some of the mathematical concepts, but Wikipedia is your friend in this regard. I was able to write a simple neural net playing TicTacToe successfully after reading the book.
Once you have the basics down, I recommend watching the Stanford lectures about CNNs. This will enable you to build more complex neural nets and optimize them.
From there on it depends on what you want to build, because you will need more specific resources. But the two resources I've provided should be enough material for the first month of study.
