Python 集合推导式中的字符串是怎样排序的？有谁知道？

列表推导式都是按for循环的顺序来排列的，可是集合推导式中除了纯数字的集合外，有字符串的集合都是乱序的，到底是按什么规律排的？有谁知道什么原理？Python 3.8.8 (tags/v3.8.8:024d805, Feb 19 2021, 13:08:11) [MSC v.1928 32 bit (Intel)] on win32 Type "help", "copyright", "credi....

Python编程：列表、集合、字典推导式的示例

推导式，其实就是将多行的循环语句放到一行写# -*- coding: utf-8 -*- # 列表推导式 lst = [i for i in range(5)] print(lst) # [0, 1, 2, 3, 4] # 相当于 lst2 = list() for i in range(5): lst2.append(i) print(lst2) # [0, 1, 2, 3, 4] ...

Python迭代器生成器,私有变量及列表字典集合推导式(二)

1 python自省机制这个是python一大特性,自省就是面向对象的语言所写的程序在运行时,能知道对象的类型,换句话说就是在运行时能获取对象的类型,比如通过 type(),dir(),getattr(),hasattr(),isinstance(). a = [1,2,3] b = {'a':1,'b':2,'c':3} c = True print(type(a),type(b),...
