Hi Reader,

After a long summer break, Tuesday Tips is back! 🎉

If you’re new around here, you can find all of my past Data Science tips at tuesday.tips. (Yes, that’s a real URL!)

Next week, I’m going to start including a “link of the week” at the top of each issue. But for today, let’s just get right to the tip!

By the way, did you travel anywhere this summer? I spent some wonderful time in Iceland! 🧊🌋🥾


👉 Tip #22: How to get coding help online

If you have a coding question in 2023, you have two main options for getting help:

  • Ask ChatGPT
  • Ask a human (via email, discussion forum, Stack Overflow, etc.)

Either way, you have a much better chance of getting a helpful answer if you know how to write a great question!

My guiding principle when writing a coding question is to tell the reader everything they need to know and nothing else. This makes it easier for the reader to be helpful, and (at least in the case of humans) increases the likelihood that you will get an answer!


My 5-step process for writing a great question

(1) Write a brief introduction: Give a quick summary of what you’re trying to accomplish and the problem you’re having.

(2) Provide a self-contained code example: Write code that can be copied, pasted, and run by the reader so that they can try it out on their own machine.

(3) Detail the expected results: Explain your expected output to the reader so that they can validate whether they have actually solved your problem.

(4) Add any important notes: Tell the reader anything they need to know about the problem that wouldn’t be obvious from the code example. This helps to steer readers away from solutions that may appear to work but don’t actually solve your problem.

(5) Write a title that summarizes the question: Whether you’re emailing a discussion group or posting on Stack Overflow, you’ll have a better chance of the right person reading your question if you write a concise and accurate title. (I suggest doing this last rather than first!)

Finally, here are some things you can optionally include:

  • An error message, if your question is about how to fix a specific error.
  • A diagram, if you think that might help to clarify your question.
  • Which software versions you are using, if you think that might be relevant.
  • Code you tried that didn’t work, if you think that might help to clarify your goal.
