New Programmer

Hello everyone. Im new to coding I want to learn bioinformatics, Is there any cheat sheet with the basics of coding, i know bioinformatics is mostly python, SQL and R but i would like to have some kind of resumed version of basics coding that fits most languages like those cheat sheets.

The best thing to do would be to take basic courses in each language and learn the concepts that are present in most languages.

SQL is quite different to Python, R and others, though.
