sorted() 作为 Python 内置函数之一,其功能是对序列(列表、元组、字典、集合、还包括字符串)进行排序。 sorted() 函数的基本语法格式如下: list = sorted(iterable, key=None, reverse=False) 1. 其中,iterable 表示指定的序列,key 参数可以自定义排序规则;reverse 参数指定以升序
dict的key必须是不可变对象。在Python中,字符串、整数等都是不可变的,因此,可以放心地作为key。而list是可变的,就不能作为key set和dict类似,也是一组key的集合,但不存储value。由于key不能重复,所以,在set中,没有重复的key。 set可以看成数学意义上的无序和无重复元素的集合 函数 如果想定义一个什么事也不做...
The objects returned bydict.keys(),dict.values()anddict.items()are view objects. They provide a dynamic view on the dictionary’s entries, which means that when the dictionary changes, the view reflects these changes. Thedict_keysobject is an iterator and looks a lot more like asetthan a...
To access the value of a specific key, you can use square brackets and the key, like this: value = my_dict["key1"]# value will be "value1" Dictionaries also offer several methods to manipulate and access their key-value pairs. Theitems()method, for example, returns a view of all t...
