So their usage seems to be obvious to most if not all(which one to choose).
reduce/map/filter obviously is not the obvious way for people from C or other imperative background, and may not be for those who never program before. However, for those who know these functions as well as the for style, it is no longer so obvious(in the sense which is better/clearer). It would then become a style choice. It can also be some policy choice, like because an organisation want to be certain that newly hired programmer(who would most likely be people from imperative background) can pick up the program easily, it is better not to use the FP style. -- http://mail.python.org/mailman/listinfo/python-list
