python中while循环 range()和while的练习 continue和break区别 判断条件 boolean类型,结果是true或者false while 判断条件:循环体 continue和break区别 1.continue 结束本次循环 继续下一次循环 continue 下面的代码不执行 2.break 结束所在内侧循环层 执行外层代码 是外侧大循环 range()和while的练习 题... ...
虽然可以将while(condition) {block};表示为if (condition) do {block} while(condition);或将do {block} while(condition);表示为if (1) {block} do {block} while (condition);,但简单的编译器通常会为这些编写相同内容的替代方法生成稍有不同的代码,不同的代码编写方法在不同的情况下会产生更好的结果。
def do_while(stuff, condition): while condition(stuff()): pass Run Code Online (Sandbox Code Playgroud) 但是1)这很难看.2)条件应该是一个带有一个参数的函数,应该由stuff填充(这是不使用经典while循环的唯一原因.) 写`while True:stuff(); 如果不是条件():break`是一个非常好的主意.谢谢! (5认同...

综上所述,我们可以通过使用do-while循环节点进行12次循环来方便的计算每月的数据,同时使用3个SQL节点分别计算近1月(30天)、近2月(60天)、近3月(90天)的数据。通过使用${dag.loopTimes}来代表当前循环到第几个月,从而在SQL节点中计算出当月第1天的分区及前1月第1天、前2月第1天、前3月第1天的分区。最...
