Hello student ,

I will highly recommend CS50 , The hardvard course available for free on EDX for learning basics of programming C python , SQL and many more . ( See course details for more )

-Few books ( you can easily find it's free PDFs online by googling the names ) and free video courses .

-Docs are available on the official coding language sites .For example ( Search on google for " Python docs ")

Hope it will help you , for further queries feel free to ask !
