[Python]有关Set常用命令，,my_set = s

my_set = set() #create a new set, 虽然set的显示结果为{item, item1...}，但是不能用{}来创建集合，应该{}默认是创建dictprint(help(my_set)) #查看帮助my_set.add(‘jerry‘) #添加元素用add,而非list中的appendmy_set.add(‘elaine‘)my_set.add(‘george‘)my_set.add(‘kramer‘)my_set.add(‘hawkeye‘)my_set.add(‘henry‘)my_set.add(‘radar‘)my_set.add(‘frank‘)print(my_set)for name in sorted(my_set, reverse=False):    print(f‘\t{name}‘)print(len(my_set)) #计算元素个数popped_item = my_set.pop() #pop规则是什么？哪个元素被删除了, 随机剔除print(popped_item)print(my_set)my_set.remove(‘hawkeye‘) #删除指定元素#my_set.insert(0, ‘hot_lips‘) 这是不行的，set没有inset methodprint(my_set)my_set.clear() #清空全部元素print(my_set)del my_set #删除my_setmy_list = [‘spurn‘, ‘charade‘, ‘spurn‘, ‘rechazar‘, ‘cáscara‘, ‘corteza‘, ‘corteza del limón‘, ‘aseo de casa‘, ‘aseo personal‘]your_set = set(my_list) #用set(list)可以把list转换成集合，好处在于剔除重复元素 remove duplicatesprint(len(my_list))print(len(your_set))print(‘words in my_list include: ‘)for index, item in enumerate(my_list):    print(f‘\t{index+1}.{item}‘)#另外还有集合的交集，并集，补集
