Dictionary是类似于List,但是Dictionary不用offset访问,而是用唯一的key访问对应的value,它的元素是key-value的一对值,key必须是不可变的Python对象,如boolean,integer,string,Tuple等。 创建 使用{} empty_dict = {}#创建一个空Dictionary e2c_dict = {"love":"爱","you":"你"} 1 2 使用dict() 从其他类...
Create Sets in Python To create sets in Python, place all the elements within curly braces {}, separated by commas. A set can include unlimited items, such as integers, floats, tuples, and strings. However, mutable elements such as lists, sets, and dictionaries cannot be used as elements ...
lists,tuples and sets of Python (python2.7.x) Lists 列表 列表是一个有序序列(集合),可变的(可以修改),可以理解为其他语言中的数组类型,但是列表更灵活更强大。 列表由方括号[]来定义的,它的元素可以是任意类型或对象,一个列表中可以包含混合元素。 例: x = [] 创建空列表 x = [1, 2] x = ['a...
Note: The expression set() produces a set with no elements, and thus represents the empty set. Python reserves the {} notation for empty dictionaries.Note: You can use add(), delete(), remove(), discard() like functions in set also same as likewise in lists etc.Example:...

A set is a built-in data structure in Python with the following three characteristics. Unordered:The items in the set are unordered, unlike lists, i.e., it will not maintain the order in which the items are inserted. The items will be in a different order each time when we access the...
