} FOR_LOOP ||--o{ NESTED_LOOP : contains NESTED_LOOP ||--o{ BREAK_STATEMENT : uses 结尾 通过上述步骤和实例代码,你应该能够清晰地理解在Python的for循环结构中,如何有效地使用break语句来控制程序的执行流。无论是在简单的列表迭代,还是在复杂的嵌套循环中,合理使用break可以帮助你提高代码的效率和可读性。
However, the loop continues to the next iteration. This is whyC++is displayed in the output. VisitPython break and continuearticle to learn more. Nested for loops A loop can also contain another loop inside it. These loops are called nested loops. ...
This is where a nested for loop works better. The first loop (parent loop) will go over the words one by one. The second loop (child loop) will loop over the characters of each of the words. words=["Apple","Banana","Car","Dolphin"]forwordinwords:#This loop is fetching word from...
In the nested loop, the number of iterations will be equal to the number of iterations in the outer loop multiplied by the iterations in the inner loop. In each iteration of the outer loop inner loop execute all its iteration.For each iteration of an outer loop the inner loop re-start a...
for i in range(5): for j in range(5): if some_condition: # 替换为实际条件 raise BreakLoop except BreakLoop: pass 如何在Python中使用标志变量来控制多层循环的终止? 通过设置一个标志变量,可以在内层循环检测到需要终止的条件时,改变标志的状态,然后在外层循环中检查这个标志变量,从而实现控制。示例代码...
for i in range(1, 11): # nested loop # to iterate from 1 to 10 for j in range(1, 11): # print multiplication print(i * j, end=' ') print() 1. 2. 3. 4. 5. 6. 7. 8. 输出: 在这个程序中,外部 for 循环是从 1 到 10 迭代数字。 range() 返回 10 个数字。 所以外循环...
