问题 I need to get date objects for the first and last day in the current year. Currently I'm using this code which works fine, but I'm curious if there's a nicer way to do it; e.g. without having to specify the month/day manually. from datetime import date a = date(date.today().year, 1, 1) b = date(date.today().year, 12, 31) 回答1: The only real improvement that comes to mind is to give your variables more descriptive names than a and b . 回答2: There is nothing in the python library but there are
