【python】python 一行 if else 語法 (one line if else) sample code (內含範例程式碼) 前言這個算是比較fancy的功能,有時為了排版漂亮、或邏輯已經很簡單,不需要撰寫多行程式碼時,才會使用。Sample Code 使用方法
(1)单分支结构if语句 (2)二分支结构if-else语句 (3)多分支结构 2、python里面所有非零的数值或者其他非空的是数据类型都等效为True,而只有数值0等效为False,所以在判断语句里面需要注意输出的成立与不成立。 3、python里面的循环语句分为遍历循环和无限循环 (1)遍历循环结构:for n in x (2)无无限循环:while...
