循环(Loop):在编程中,循环是一种控制结构,它允许代码块重复执行,直到满足某个条件。 正向循环:从开始到结束按照既定顺序执行。 反向循环:在完成正向循环后,按照相反的顺序执行。 实现方法 我们可以使用数组或列表来存储循环中的元素,并通过索引来控制正向和反向的遍历。 示例代码(Python) 代码语言:txt 复制 # 假设...
while有计数循环和无限循环两种,无限循环可以用于某一服务的主程序一直处于等待被连接的状态 break代表跳出本层循环,continue代表跳出本次循环 while循环在没有被break打断的情况下结束,会执行else后代码 3.for语句 3.1 功能 for 循环提供了python中最强大的循环结构(for循环是一种迭代循环机制,而while循环是条件循环,...
它通常与While语句配对使用,放在While语句的下一行。 以下是一个使用While循环和End While语句的示例代码(使用Python语言): 代码语言:txt 复制 i = 0 while i < 5: print(i) i += 1 end while print("Loop ended.") 在上面的代码中,我们使用While循环打印从0到4的数字。当i的值小于5时,循环会一直执行...
