note2: 列表推导式里可以用多个for循环,返回的则是笛卡尔积 3.生成器表达式( Generator Expressions) 我们把列表表达式的[]换成()就得到了一个新的返回对象:生成器。 Leap_Year_Generator = (item for item in range(1582, 2022) if is_leap(item)) #得到生成器的这个方法称之为生成器表达式 所以,推导式和...
set:无序且不重复的集合,就是一个只有键没有值的dict,Java的HashSet就是采用HashMap实现,但愿python不会是这样,毕竟set不需要value,省去了很多指针。 Generator: 称之为生成器,或者列表推导式,是python中有一个特殊的数据类型,实际上并不是一个数据结构,只包括算法和暂存的状态,并且具有迭代的功能。 先看看它们...
