I'm trying to run this program but i get that error massage: 'break' not properly in loop. I've searched for some answers and the reason for the mistake, break cannot be used outside a loop statement. But as you see bellow, i'm trying to use "break" in a while loop. I'm new...
I wonder the location of 'break' in this case would break only the inner 'while' loop or break even the outer 'while' loop? In this case, will it still run 'statement 1' and 'statement 2'? If not, how do I make sure it only break the inner loop and still run 'statement 1' ...
i=1while i > 0:# i永远大于0i=i + 1print(i) 这段代码就是一个死循环,变量i的值永远都大于0。 02 for循环 for循环用于遍历一个集合,依次访问集合中的每个项目。for循环的格式如下所示。 for变量in集合:…else:… for…in…循环的执...

loop3 j=0 j=1 j=2 3、带标签的break语句 常常用于跳出多层嵌套 注意,在带标签的break语句中,标签必须放在希望跳出的最外层之前,并紧跟一个冒号 e.g 1 public class Test { 2 public static void main(String args[]){ 3 4 read_data: 5 while(1==1){ ...
The break statement, like in C, breaks out of the innermost enclosing for or while loop.Python中断语句与C语言类似，打破了最小封闭for或while循环。Loop statements may have an else clause; it is executed when the loop terminates through exhaustion of the list (with for) or when the condition ...

break将执行移出标记的循环。 在嵌入式循环中,其结果与break关键字 (keyword) 单独使用时的结果不同。 此示例包含语句while的 语句for: PowerShell :myLabelwhile(<condition1>) {for($itemin$items) {if(<condition2>) {breakmyLabel }$item=$x# A statement inside the For-loop} }$a=$c# A statement...
