Python中有6个标准的数据类型：Number（数字）、String（字符串）、List（列表）、Tuple（元组）、Set（集合）、Dictionary（字典），每种类型有其固有的属性和方法，学会这六种数据类型及基础的方法，很多代码基本上都能看得懂，很多功能也都能实现了。要是实现面向百度编程到面向自己编程的转变，必须搞搞清楚这六大...
numbers.sort() print(numbers) 输出:[1, 2, 3, 4, 5] 2. 字典排序 对于字典,我们可以使用sorted()函数对字典的键、值或键值对进行排序。sorted()函数接受一个字典作为参数,并通过key参数指定排序依据。 对字典的键进行排序 d = {'one': 1, 'three': 3, 'two': 2} ...
