Beginning of software developing

This shouldnt be only for me, i want people with intrest like me find this thread helpful.
So... i have intrest in software developing and going to school to learn it (learned IT for 1 year, there was no coding mostly servers and Graphics design), but i have no clue what i should know about it and what language should i use, i have heard that C++ and Python are the common ones to use.
Main question/wish is if someone is willing to spend time commenting useful sites or e-books for learning or have any tips from your own sleeve
Maybe in the future i can share information to others and maybe even create my own codes for games etc.
Also can ask questions about me if needed.

I would second the recommendation of using Unity, its my preference for small games and side projects and demos i have found my self making over the years.
C# is a great starting language to learn and with the easy UI of Unity you can either keep it simple and focus more on using the GUI or push yourself and do more in code (Which i would reccommend).

Everything and anything can be Googled for Unity.

any great online school or tutoring?

I think everyone should learn python due to how flexible it is, also get free udemy course or just read an ebook
google best python ebooks and u'll find many great ones
personally think python is the best
GL with ur endeavors
