Like other programming languages, in Python, break statement is used to terminate the loop's execution. It terminates the loop's execution and transfers the control to the statement written after the loop.If there is a loop inside another loop (nested loop), and break statement is used ...

break 语句 Python break语句,就像在C语言中,打破了最小封闭for或while循环。 break语句用来终止循环语句,即循环条件没有False条件或者序列还没被完全递归完,也会停止执行循环语句。 break语句用在while和for循环中。 如果您使用嵌套循环,break语句将停止执行最深层的循环,并开始执行下一行代码。 Python语言 break 语句...
BREAK_STATEMENT { +String action } NESTED_LOOP { +String outer +String inner } 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...
words = CircularList() words.append('eggs') words.append('ham') words.append('spam') counter = 0 for word in words.iter(): print(word) counter += 1 if counter > 1000: break 一旦我们打印出 1,000 个元素,我们就跳出循环。总结在本章中,我们已经研究了链表。我们研究了构成列表的概念,如...
It's worth noting that if Python doesn't terminatewhileloops, they can loop endlessly. Therefore, when relying on abreakstatement to end awhileloop, you must ensure Python will execute yourbreakcommand. Let's consider our previous example, where we wrote a script to find the first ten multi...
Break Statement in Python The Break statement in Python allows you to exit a loop when a particular condition is met or triggered. The Break statement is placed within the block of the loop statement, after a conditional “if” statement that you want to check before exiting the loop. Here...
while 1: try: n = int(input("enter a integer (0-exit): ")) print(n) if n == 0: break except: print("try again...") ''' enter a integer (0-exit): 5 5 enter a integer (0-exit): a try again... enter a integer (0-exit): 0 0 ''' 示例一。 用实例调用方法 calc(...
statement(s) break:就像在C语言中,打破了最小封闭for或while循环 continue :跳出本次循环 pass:空语句,是为了保持程序结构的完整性。pass 不做任何事情,一般用做占位语句。 函数 定义函数 def functionname( parameters ): "函数_文档字符串" function_suite ...
Generally, the control flow of a program runs from top to bottom. However, the control flow statements break the general top-to-bottom order of execution by including decision-making, looping, and more. This enables the program to first execute a specific block of code based on the ...
