how to create useful neural network program?

[hsunteik]

I have learned many neural network tutorial and watched some videos,and i really understand them,but all the tutorial that saw before only teach me about the concepts and how it works,but none of them teach me how to create a actual program with it.
Can anyone give me a tutorial that teach me how to make ACTUAL program with neural network or giving me the source code(in python) of any neural network program?
