# This is a program to illustrate the useage of continue in Python. # If you want to stop executing the current iteration of the loop and skip ahead to the next # continue statement is what you need. # *** for i in range (1,6): print print 'i=',i, print 'Hello,how', if i...
$ python conditional.1.py I need to call my manager! 由于late是True,print语句被执行了。让我们扩展一下这个例子: # conditional.2.pylate =Falseiflate:print('I need to call my manager!')#1else:print('no need to call my manager...')#2 这次我将late = False,所以当我执行代码时,结果是不...

whileTrue:suite_to_repeat 1. 2. 无限循环主要是用在Server/Client模式中Server端的设计,用以等待来自客户端的连接,当然如果有必要的话也是可以通过break语句来结束循环的。 6.for语句 for语句提供了Python中最强大的循环结构,它可以遍历序列成员,可以用在列表解析和生成器表达式中,它会自动地调用迭代器的next()方...
for x in s: # `x` is an iteration variable ...statements 在每次迭代中,迭代变量的先前值会被覆盖(如果有)。循环结束后,迭代变量保留最后一个值。 break 语句 可以使用 break 语句提前跳出循环。 for name in namelist: if name == 'Jake': break ... ... statements ...
Continue running the program until the next breakpoint is reached by usingContinue(F5). Because you have a breakpoint set in theforloop, you break on the next iteration. You can confirm the program is continuing to execute by observing the changing value for thesvariable in ...
