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 ...
breakis an excellent way of controlling your scripts, hence why it's called a control statement. It terminates whichever loop it's placed within, causing Python to resume whatever line of code comes after the loop. For situations that make use of nested loops,breakwill only terminate the inne...
Here, we have two loops, outer loop is "while True:" which is handling the multiple inputs and inner loop is using to print the table of given number – as input is 0 – inner loop will be terminated. # python example of break statement count = 1 num = 0 choice = 0 while True...
However, there are scenarios where you need more control over the flow of your loops. For instance, you might encounter a situation where you need to exit a loop prematurely, skip the current iteration, or simply have a placeholder for future code. Python provides three powerful statements to ...

In this example, we have two nested for loops. The inner loop will break when both i equals 1 and j equals 1. Therefore, the output will show values for i and j until that condition is met. This method is useful when you want to exit just one level of the loop while keeping the...
Before diving intobreak, continue, and pass, let’s briefly review Python loops. Loops in Python allow us to execute a block of code multiple times. The two primary types of loops are: For Loop– Iterates over a sequence (list, tuple, dictionary, set, or string). ...
In programming, the break and continue statements are used to alter the flow of loops: break exits the loop entirely continue skips the current iteration and proceeds to the next one Python break Statement The break statement terminates the loop immediately when it's encountered. Syntax break ...
