I finally understand nested comprehensions

loops each time I see a complicated list comprehension, and they are trivial to read and write! It still, I admit, feels odd that the expression, which would be deep inside of normal


loops, goes in front of them in a comprehension instead. And I am not sure that double comprehensions should become part of my normal coding style. (How many other Python programmers understand them? Has everyone else been using them without problems?) But they are a neat trick to have up my sleeve when I need to iterate over an image quickly and want to pack everything into a single, easily-bloggable expression.
