I have recently asked this question: How to flatten a list of lists without using for loops, where I was looking for suggestions on how to improve the performance and readability of a snippet of Python code I had written.
I understand that the original question was opinionated, and I now know this is not the type of questions we are looking for on the forum, however I was wondering if there are ways I could improve the question (I have been banned from asking further questions on SO, and this is a community I really enjoy using, both asking and answering questions.)
