字典(Dictionary):无序的键值对集合,键是唯一的且不可变,值可以是任意对象。 集合(Set):无序且不重复的元素集合,支持集合运算(如并集、交集)。 # 列表示例my_list=[1,2,3,'Python',4.5]# 字典示例my_dict={'name':'Alice','age':25,'city':'New York'}# 集合示例my_set={1,2,3,4,5} ...
dict(zip(keyslist, valueslist)) # Zipped key/value tuples form (ahead) 方法六:使用fromkeys函数,很少用到 >>> dict.fromkeys(['a', 'b'], 0) {'a': 0, 'b': 0} 25,使用dictionary comprehensions来创建dictionary的例子: 25.1 别忘了冒号。。
