I don't see a conflict between loops, list comprehensions and other shortcuts - use the syntax sugar where it makes the code simpler/easier to read, otherwise stick to plain loops. My own rules for "list/dict comprehension" versus "loops" versus "generator expressions" are the following: * use a loop where you are interested only in the side-effects or where it will make the code easier to read * use generator expressions where you don't really need to instantiate a list, for example when you are just iterating over the result and throwing it away. * use list or dict comprehensions where you need to build and save a list/dict and the resulting code does not resemble a lisp program (where the choice does not make the program harder to read).
