There is also another group of trivial questions, which IMHO should be closed:

• how do I do XY - usually something trivial in principle, just requiring the work to be done, and usually again not a singular problem: like Get data from database and display with odd or even id number

P.S.: and yet another group, but this is not for closing, because then it can be improved by the asker:

• plz debug my looong code
• often trivially solvable by debug prints
• without any effort to narrow the code/question down to singular problematic case
