I hope they know how to learn...
Well...
Sometimes they are just fear of trying to code, reading error messages. For this kind of people, you could just guide them and explain to them.
Sometimes they are lazy to read books and documents, or lazy to search the web for existing solution. For this kind of people, you guide and explain too... But, once they ask the same kind or level of question again, you should keep yourself from think about their question and from think about why they always do something so $%^&.
This is my experience earned from my pervious life...
