这个例子中,while True创建了一个无限循环,但当count达到5时,break语句将终止循环。 二、BREAK IN NESTED LOOPS 当使用嵌套循环(即一个循环中包含另一个循环)时,break语句只会退出当前所在的最内层循环,而不会影响外层循环的执行。 2.1 EXAMPLE OF BREAK IN NESTED FOR LOOPS 考虑以下嵌套循环的例子: for i in...
python def nested_loops(): for i in range(5): for j in range(5): if j == 2: return # 直接返回,相当于跳出所有循环 nested_loops() print("函数已返回,相当于跳出所有循环") 3. 使用异常处理 定义一个自定义异常,并在需要跳出外层循环的地方抛出该异常。在外层循环中捕获该异常,从而跳出循环。
在Python 中跳出嵌套循环的 5 种方法(5 Ways To Break Out of Nested Loops in Python) 1. 添加标志变量 Add a Flag Variable 2. 抛出异常 Raise an Exception 3. 再次检查相同条件 Check the Same Condition Again 4. 使用 For-Else 语法 Use the For-Else Syntax 5. 将其放入函数中 Put It Into a ...
The break statement in Python terminates the nearest enclosing loop prematurely. This tutorial explains how to use break to exit loops, demonstrates nested loop scenarios, and provides practical examples of flow control. When executed, break immediately stops loop iteration and transfers execution to ...
Nested Loop Break How can we break a loop directly from another nested loop? e.g: for(int i=0;;i++){ for(int j=0;;j++){ if(matrix[i][j]==100){ goto break_pt; //exit both loops } else if(j==10){ break; } } } break_pt: 8th Jul 2017, 3:45 PM Karl T. + 5 Yo...
